* Add Windows system chrome patchers (Harmony)

Introduce support for toggling the system chrome on Windows using Harmony patchers. Adds Lib.Harmony.Thin to package props and project, new patcher infrastructure (ChromePatchState, PatcherEntrance) and two Harmony patches that disable FluentAvalonia's Windows chrome when configured. Program.cs now loads the chrome setting and installs patchers conditionally on Windows/x86-x64. Settings viewmodel and view updated: expose IsWindowsOs, require restart on appearance changes, migrate SettingsWindow to FAAppWindow and adapt titlebar/layout (include Windows caption placeholder and footer menu items). Also add a .gitkeep and a build log file.

* Refactor settings window UI and theming

Improve theming and layout for the Settings window and related services.

- MaterialSurfaceService: add special material parameters for SettingsWindowBackground (lower alpha, no blur) and avoid hot-switching real backdrops for non-settings windows.
- GlassEffectService: add AdaptiveSettingsWindowTintBrush + ResolveSettingsWindowTintAlpha to provide optional content tinting tied to system material mode.
- SettingsWindowService: refactor theme application into ApplyThemeVariantAndResources, ensure settings window material is applied at show/activate times, and tidy theme/resource application flow.
- SettingsWindow.axaml / .axaml.cs: restructure title bar (separate Grid.Row=0 border) and FANavigationView host, add pane-footer toggle button for :minimal layout, use dynamic corner radius resource, and update toggle/visibility/icon logic and responsive layout code.
- SettingsPages: remove some IconText usages and adjust margins; use DesignCornerRadiusLg for update card corner radius.
- Add NuGet.Config to set local globalPackagesFolder and ignore .nuget/packages in .gitignore.

These changes aim to improve visuals, avoid backdrop overdraw, and make the settings window behavior consistent across themes and layouts.

* Add localization and localize settings pages

Add many new localization keys (en-US and zh-CN) for notifications, developer tools, about page, status bar, and video wallpaper. Update Notification, Dev, About and StatusBar view models to use LocalizationService, expose localized ObservableProperties, and refresh localized text at construction. Localize selection options and test notification texts, and fix notification severity handling. Wire up XAML to the new localized properties (About/Dev/StatusBar pages) and update the settings page title for notifications. Also adjust copyright line generation and replace hardcoded placeholders with bound Watermark properties.

* Redesign settings window with fluent shell & search

Rebuild the settings window as a Fluent shell: adds a custom 48-DIP titlebar with Back, pane toggle, icon/title, search box, restart/more menu, and caption-button spacer; moves compact pane toggle into the titlebar and preserves FANavigationView as the primary navigation surface. Introduces a SettingsSearchService (with UI AutoComplete integration, search indexing, navigation-by-result, and search result highlighting) plus focused tests for search filtering and theme material normalization. Adds navigation history/back stack, updates SettingsViewModels for new bindings and localization keys, and updates General/Apearance pages to expose new strings and options. Implements an "auto" system material mode: default in AppSettingsSnapshot, new MaterialAuto constants and normalization/resolution logic in ThemeAppearanceValues, WindowMaterialService and MaterialSurfaceService adjustments to prefer Mica on Win11 and Acrylic on Win10 using TransparencyLevelHint. GlassEffectService and AppearanceThemeService updated to use effective material mode and to track live theme state changes. Adds localization entries (en-US, zh-CN), spec/tasks docs, and other UI/style tweaks to support the redesign.

* Add OOBE startup presentation and settings merge

Introduce a new OOBE step for "Startup & Presentation" that exposes startup and UI preferences in OobeWindow (toggles for taskbar, slide/fade transitions, fused popup, and autostart). Add HostAppSettingsOobeMerger to read/write Host settings.json (PascalCase fields) and MergeStartupPresentation behavior, plus LauncherWindowsStartupService to sync the current Launcher into the Windows Run key on Windows. Wire UI handlers, persist choices on Next, and load defaults when entering the step. Include unit tests for the merger, adjust SettingsWindow navigation pane/toggle handling, and update docs/LAUNCHER.md to describe the new OOBE step and implementation files.

* Move whiteboard persistence to file storage

Switch whiteboard note storage from legacy DB rows to per-note JSON files and add migration support. Update WhiteboardNoteSnapshot schema (version bump, viewport, canvas, expires, PathSvgData) and change IWhiteboardNotePersistenceService.SaveNote to return bool to surface write failures (e.g. read-only files). Implement file-based WhiteboardNotePersistenceService with legacy DB migration/cleanup, retention handling, and logging. Add comprehensive unit tests for persistence, stroke path builder, SVG import and viewport helper. Also add ThirdParty/DotNetCampus.InkCanvas project and reference it in the main csproj, and bump PostHog package to 2.6.0.

* Introduce render gate and chart caching

Replace UI DispatcherTimer polling with a StudySnapshotRenderGate across multiple widgets to queue and apply only the latest analytics snapshot; components updated include StudyDeductionReasonsWidget, StudyEnvironmentWidget, StudyInterruptDensityWidget, StudyNoiseCurveWidget. Add StudySnapshotRenderGate implementation to coordinate rendering and monitoring leases and update subscription/lease lifecycle handling (subscribe/unsubscribe, Acquire/Dispose leases, Clear/Dispose gate). Rewrite chart controls (StudyNoiseCurveChartControl and StudyNoiseDistributionScatterChartControl) to use stable logical-time origins, split series into static vs dynamic tails, add geometry/sample caching, stable jitter/coordinate mapping helpers, and expose internal helpers & counts for testing. Add unit tests (StudyComponentRenderingTests) covering the render gate and chart behaviors (layer counts, logical X mapping, stable jitter, cache rebuild). These changes improve rendering correctness and performance by avoiding redundant renders and enabling deterministic chart layout.

* Use MaterialColorSnapshot in appearance flow

Introduce unified material/color spec and tests, and refactor appearance plumbing to use MaterialColorSnapshot as the single source of truth. Add .trae material-color-service spec/checklist/tasks and integration/unit tests for plugin mapping and appearance VM behavior. AppearanceChangedEvent extended with new appearance change flags and HasChanged logic. ComponentEditorMaterialThemeAdapter rewritten to accept MaterialColorSnapshot and derive palette from snapshot data. Simplify AppearanceSettingsPageViewModel and related view code: remove legacy preview/custom-seed UI logic, preserve material/color fields when updating theme or corner radius, and update save calls to use with-expressions. Update ComponentEditorWindow to use adapter-provided OnPrimary brush and minor docs updates.

* Add material color services, plugin DTOs, and tests

Introduce IPC wire-format appearance DTOs (PluginIsolation.Contracts) and clarify they are distinct from the runtime PluginSdk snapshot. Update PluginSdk comments to document the runtime-facing snapshot shape. Change ComponentColorSchemeHelper to use the HostMaterialColorProvider and add an overload that accepts a MaterialColorSnapshot. Add new services and pipelines (MaterialColorService, MaterialSurfaceService, WindowMaterialService, WallpaperColorPipeline) and refactor AppearanceThemeService to depend on MaterialColorService while removing legacy internal implementations. Add multiple unit tests (ComponentColorSchemeHelper, PluginAppearanceBoundary, SettingsCatalogService, WallpaperSettingsPageViewModel) and update localization resources with new material_color and wallpaper keys.

* Add CODE_WIKI and update localization

Add a comprehensive CODE_WIKI.md documenting project architecture, modules, startup flow, plugin system, testing and developer workflows. Update localization resources (en-US.json, zh-CN.json) with new/translated keys for wallpaper controls (custom color UI), material & color settings (semantic roles, surfaces, refresh/polling state), appearance (corner radius), status bar font size options, privacy policy text, component library labels, clock settings, and new language entry (Korean). Also modify settings-related ViewModels and Settings page views to surface these new features and texts (MaterialColorSettingsPageViewModel.cs, SettingsViewModels.cs, WallpaperSettingsPageViewModel.cs, MainWindow.SettingsHardCut.Stubs.cs, ComponentsSettingsPage.axaml, WallpaperSettingsPage.axaml).

* Add Data settings page and storage scanner

Introduce a new "Data" settings page to visualize and manage local app storage. Adds DataStorageService (scanning, disk info, clean operations), DataSettingsPageViewModel, XAML view and code-behind, and HexToColor/HexToBrush converters; registers converters in App.axaml. Also update localization strings for the new page and add icon mapping so the settings entry uses the Database icon. Enables per-category and global cleaning workflows and formatted size display.

* Add IPC backoff/retries and safer disposal

Introduce exponential backoff, jitter and retry logic across IPC components to improve robustness and avoid tight retry loops; make disposal idempotent and add connection guards. Key changes:
- LauncherCoordinatorIpcServer / LauncherIpcServer: add backoff constants, ComputeBackoff(), consecutive error tracking and delayed retries with jitter.
- LanMountainDesktopIpcClient / LauncherIpcClient: add connect retry loops, timeouts, delayed retries, improved error logging, and use ArrayPool for buffered async writes; ensure proper cleanup on failures.
- PublicIpcHostService: add disposed flag, guard OnPeerConnected and Dispose, and clear connected peers on dispose.
- Add many auto-generated commit analysis docs under docs/auto_commit_md and new scripts for analyzing/generating commit docs.
These changes aim to make IPC connection handling more resilient and resource-safe.

* Add preview controls and settings UI tweaks

Introduce GridPreviewControl and CornerRadiusPreviewControl for visual previews and wire them into the Components settings (add ScreenAspectRatio, CornerRadiusPreviewValue, and screen aspect init). Refactor ComponentsSettingsPage UI to show live previews. Improve DataSettingsPage layout and storage bar logic (use item percentages directly, include remaining segment, adjust visuals and visibility triggers). Simplify LauncherSettingsPage header/appearance layout. Add SECURITY_AUDIT_REPORT.md, analysis summary, mockup HTML, and a local .claude settings file.

* Add install checkpoint/resume and DDSS workflows

Introduce install checkpoint support and resume logic for updates, plus related locking and validation. Adds InstallCheckpoint model, AppJsonContext serialization, and UpdatePaths helpers for deployment lock, apply-in-progress lock and install-checkpoint path. UpdateEngineService gains checkpoint load/save/delete, incoming-state validation, resume logic for PLONDS and legacy updates, apply lock handling, and safer cleanup; ApplyPendingPlondsUpdateAsync and ApplyPendingUpdate flow updated accordingly. Add DeploymentLock contract and extend UpdateState with pause/resume/cancel helpers. Tests updated to cover stale/valid checkpoint resume and legacy/PLONDS flows. CI: enhance ddss-publish to detect release channel, validate S3 assets, prepare and atomically publish channel pointer; add ddss-rollback workflow to publish rollbacks; adjust plonds-build concurrency and release events.

+## 系统设计特例约束 (System Design Exceptions)
 
 > [!IMPORTANT]
-> **设置窗口强制约束**：
-> 设置窗口 (`SettingsWindow`) 始终使用 Fluent 圆角 Token，不受用户全局圆角设置影响。这确保设置 UI 作为标准 Windows 应用窗口与 Fluent Design 一致。
+> **局部作用域隔离原则 (Scope Isolation)**
+> 为了确保系统级配置面板、向导及管理界面的设计规范性，部分特例区域必须**始终使用 Microsoft Fluent Design System 预设**，不受用户在“外观设置 -> 全局圆角”中所选风格的影响：
+> 
+> 1. **设置窗口 (`SettingsWindow`)**：作为主配置中心，强制应用 Fluent 圆角，使其展现标准 Windows 应用的高级感与一致性。
+> 2. **融合桌面组件库 (`FusedDesktopComponentLibraryWindow` / `FusedDesktopComponentLibraryControl`)**：小组件库的管理添加窗口本身属于系统级向导，强制采用 Fluent 圆角设计（如外壳圆角为 `DesignCornerRadiusLg`，内部按钮为 `DesignCornerRadiusSm`），保证交互的高级感与系统级管理界面对齐。
+> 3. **系统弹出对话框 (`ContentDialog` / `FAContentDialog`)**：例如设置界面的重启确认、编辑桌面时的删除页面二级确认、电源菜单的二次确认等，通过全局 XAML 样式统一覆盖其所使用的 `OverlayCornerRadius` (8px)、`ControlCornerRadius` (4px) 以及相关的 `DesignCornerRadiusXxx` 令牌，以确保这些高优先级确认弹窗在任意窗口上层弹出时均保持 Fluent 风格。
+> 4. **多开提示窗口 (`MultiInstancePromptWindow`)**：当多次启动软件时弹出的二级拦截警示窗口，属于独立启动器进程中的系统级安全提示，强制在 Window Resources 中硬编码重载为 Fluent 风格对应的圆角参数（如边角 8px，交互按钮 4px）。
+
+### 实现机制 (Implementation Mechanism)
+
+在上述特例窗口的初始化过程中，通过在其根网格/容器元素（如 `RootGrid`）下调用 `ApplyFluentCornerRadius()`，在局部作用域内覆盖所有的 `DesignCornerRadiusXxx` 资源键为 Fluent 阶梯对应的值：
+
+```csharp
+private void ApplyFluentCornerRadius()
+{
+    if (RootGrid is null) return;
+
+    var tokens = AppearanceCornerRadiusTokenFactory.Create(
+        GlobalAppearanceSettings.CornerRadiusStyleFluent);
+    
+    RootGrid.Resources["DesignCornerRadiusMicro"] = tokens.Micro;
+    RootGrid.Resources["DesignCornerRadiusXs"] = tokens.Xs;
+    RootGrid.Resources["DesignCornerRadiusSm"] = tokens.Sm;
+    RootGrid.Resources["DesignCornerRadiusMd"] = tokens.Md;
+    RootGrid.Resources["DesignCornerRadiusLg"] = tokens.Lg;
+    RootGrid.Resources["DesignCornerRadiusXl"] = tokens.Xl;
+    RootGrid.Resources["DesignCornerRadiusIsland"] = tokens.Island;
+    RootGrid.Resources["DesignCornerRadiusComponent"] = tokens.Component;
+}
+```
+
+这样使得所有内部子控件使用 `DynamicResource` 引用这些圆角资源时，解析到的都是隔离后且固定的 Fluent 设计弧度，实现不受全局用户偏好影响的精准渲染。
 
 ## 开发准则 (Implementation Rules)
 
 > [!IMPORTANT]
 > **1. 桌面组件强制约束**：
-> 所有桌面组件（Widget / Desktop Component）的根容器边框必须使用 `{DynamicResource DesignCornerRadiusComponent}`。严禁对其进行任何比例运算或系数乘积（如 `* scale`），必须保持固定。
+> 所有桌面普通组件（Widget / Desktop Component）的根容器边框在设计时，必须统一且仅使用 `{DynamicResource DesignCornerRadiusComponent}`。严禁对其进行任何比例运算或系数乘积（如 `* scale`），以确保用户的全局圆角缩放设置能被正确、成比例地应用。
 
 > [!TIP]
 > **2. 圆角嵌套规则**：
 > 当一个容器包裹另一个元素时，外层圆角应比内层圆角大一个阶梯。例如：
-> - 外部使用 `DesignCornerRadiusLg`
-> - 内部紧贴边缘的内容应使用 `DesignCornerRadiusMd`
+> - 外部大容器使用 `DesignCornerRadiusLg`
+> - 内部小卡片使用 `DesignCornerRadiusMd`
+> - 内部紧贴边缘的小图标或按钮使用 `DesignCornerRadiusSm`
 > 这样可以保证两条圆弧的圆心趋于重合，视觉重心更稳固。

+- 优先匹配预定义映射，提升性能
+
+#### 变更 2: 变量重命名
+```diff
+- if (Enum.TryParse<Icon>(firstComponent.IconKey, ignoreCase: true, out var icon))
++ if (Enum.TryParse<Icon>(firstComponent.IconKey, ignoreCase: true, out var resolvedIcon))
+```
+- 避免与新添加的 `icon` 变量冲突
+
+---
+
+### 2. LanMountainDesktop.Tests/ComponentCategoryIconResolverTests.cs
+
+**新增单元测试**:
+
+#### 测试 1: Date 分类图标解析

+[Fact]
+public void ResolveCategoryIcon_Date_ResolvesCorrectly()
+{
+    var result = ComponentCategoryIconResolver.ResolveCategoryIcon("Date", []);
+    Assert.Equal(Icon.Calendar, result);
+}
+```
+
+#### 测试 2: Study 分类图标解析
+```csharp
+[Fact]
+public void ResolveCategoryIcon_Study_ResolvesCorrectly()
+{
+    var result = ComponentCategoryIconResolver.ResolveCategoryIcon("Study", []);
+    Assert.Equal(Icon.Book, result);
+}
+```
+
+**测试覆盖**:
+- ✅ Date 分类 → Calendar 图标
+- ✅ Study 分类 → Book 图标
+- ⚠️ 建议：添加其他预定义映射的测试用例
+
+---
+
+### 3. LanMountainDesktop/Views/ComponentLibraryWindow.axaml
+
+**修复**: 控件类型名称更新
+```diff
+- <fi:SymbolIcon Symbol="{Binding Icon}"
++ <fi:FluentIcon Icon="{Binding Icon}"
+```
+- **变更**: `SymbolIcon` → `FluentIcon`
+- **原因**: 保持 API 一致性，使用最新的 FluentIcons.Avalonia API
+
+---
+
+### 4. LanMountainDesktop/Views/FusedDesktopComponentLibraryWindow.axaml
+
+**添加圆角属性**:
+```diff

+```
+应用到主 Border 容器，确保与其他 UI 组件的圆角风格一致。
+
+---
+
+### 5. LanMountainDesktop/Views/FusedDesktopComponentLibraryWindow.axaml.cs
+
+**新增圆角应用逻辑**:
+
+#### 变更 1: 添加依赖
+```csharp
+using LanMountainDesktop.Appearance;
+using LanMountainDesktop.Settings.Core;
+```
+
+#### 变更 2: 构造函数中调用圆角应用
+```csharp
+public FusedDesktopComponentLibraryWindow()
+{
+    InitializeComponent();
++   ApplyFluentCornerRadius();
+    // ...
+}
+```
+
+#### 变更 3: 新增 ApplyFluentCornerRadius 方法
+```csharp
+private void ApplyFluentCornerRadius()
+{
+    if (RootGrid is null)
+    {
+        return;
+    }
+
+    var tokens = AppearanceCornerRadiusTokenFactory.Create(
+        GlobalAppearanceSettings.CornerRadiusStyleFluent);
+    RootGrid.Resources["DesignCornerRadiusMicro"] = tokens.Micro;
+    RootGrid.Resources["DesignCornerRadiusXs"] = tokens.Xs;
+    RootGrid.Resources["DesignCornerRadiusSm"] = tokens.Sm;
+    RootGrid.Resources["DesignCornerRadiusMd"] = tokens.Md;
+    RootGrid.Resources["DesignCornerRadiusLg"] = tokens.Lg;
+    RootGrid.Resources["DesignCornerRadiusXl"] = tokens.Xl;
+    RootGrid.Resources["DesignCornerRadiusIsland"] = tokens.Island;
+    RootGrid.Resources["DesignCornerRadiusComponent"] = tokens.Component;
+}
+```
+
+**变更说明**:
+- 动态应用全局圆角设置到窗口的资源字典
+- 支持 Fluent 风格的圆角配置
+- 使用工厂模式创建圆角 Token
+

+## 代码架构分析
+
+### 新增依赖关系
+
+```
+FusedDesktopComponentLibraryWindow.axaml.cs
+├── LanMountainDesktop.Appearance
+│   └── AppearanceCornerRadiusTokenFactory
+└── LanMountainDesktop.Settings.Core
+    └── GlobalAppearanceSettings
+```

+
+**变更说明**:
+- 移除了两处 `if-else` 语句后的多余分号（`;`）
+- 这是代码风格的一致性调整
+
+---
+
+## 代码审查要点
+
+### 潜在问题
+
+1. **分号语法问题**: 此次修改移除了 Pascal Script 中 `if-else` 语句后的多余分号。虽然在某些 Pascal 方言中这可能不会导致编译错误，但删除分号是正确的做法，因为 `else` 关键字不应该与分号一起使用。
+
+### 建议
+
+- ✅ **良好实践**: 移除多余分号，保持代码风格一致
+- ⚠️ **注意**: 确保其他类似的 `if-else` 语句也遵循相同的风格
+- 📝 **建议**: 考虑在整个 ISS 脚本中进行一次全局的代码风格检查
+
+---
+
+## 影响范围
+
+- **安装程序**: 影响 Windows 安装包的打包流程
+- **用户体验**: 无直接影响
+- **功能影响**: 无功能变更，仅代码风格调整
+
+---
+
+## 总结
+
+本次提交是一个简单的代码风格优化，移除了 Inno Setup 脚本中的多余分号。虽然变更很小，但有助于提高代码质量和一致性。
+
+**建议**: ✅ 可以合并

+## 技术分析
+
+### 1. 图标解析架构改进
+
+#### 解析策略（改进后）
+
+```
+输入: categoryId (string)
+       ↓
+1. 尝试直接映射（新增）
+   - clock → Clock
+   - date → Calendar
+   - weather → WeatherSunny
+   - ...
+   ↓ 失败
+2. 获取第一个组件
+   ↓
+3. 从组件的 IconKey 解析
+   - "Folder" → Icon.Folder
+   ↓ 失败
+4. 返回默认值 Icon.Apps
+```

+- 支持多种安装场景
+- 减少不必要的运行时重新安装
+
+---
+
+## 技术分析
+
+### 1. 多路径检测架构
+
+#### 检测路径
+
+```
+1. 系统路径 (Program Files)
+   - %ProgramFiles%\dotnet
+   - %ProgramFilesX86%\dotnet
+   
+2. 用户路径 (LocalAppData)
+   - %LocalAppData%\dotnet
+   
+3. 注册表 (Windows)
+   - HKLM\SOFTWARE\dotnet\Setup\InstalledVersions
+```
+
+#### 检测框架
+
+```
+1. Microsoft.NETCore.App
+   - 控制台应用程序核心框架
+   
+2. Microsoft.WindowsDesktop.App
+   - Windows 桌面应用程序框架
+```
+
+### 2. 按用户安装支持
+
+#### 安装场景
+
+| 场景 | 系统安装 | 用户安装 | 组合 |
+|------|---------|---------|------|
+| 仅系统 | ✅ | ❌ | ✅ |
+| 仅用户 | ❌ | ✅ | ✅ |
+| 系统+用户 | ✅ | ✅ | ✅ |
+
+#### 检测策略
+
+```csharp
+// 1. 枚举所有安装根目录
+foreach (var basePath in EnumerateDotNetInstallRoots(options))
+{
+    // 2. 对每个框架检查
+    foreach (var frameworkName in RequiredSharedFrameworkNames)
+    {
+        // 3. 构建完整路径
+        var sharedFrameworkDirectory = Path.Combine(basePath, "shared", frameworkName);
+        
+        // 4. 标记来源
+        var isPerUser = IsPerUserPath(basePath);
+        
+        // 5. 检测运行时
+        AddDirectoryRuntimes(sharedFrameworkDirectory, frameworkName, 
+            isPerUser ? "per-user" : "system", detected);
+    }
+}
+```
+
+### 3. 优先级策略
+
+#### dotnet host 优先级
+
+1. **系统路径优先** (Program Files)
+   - 更稳定，适合多用户场景
+   - 减少权限问题
+
+2. **用户路径备选** (LocalAppData)
+   - 如果系统路径不存在，使用用户路径
+   - 支持单用户安装

+
+---
+
+## 技术分析
+
+### XAML 架构改进
+
+#### 1. 布局结构优化
+```xml
+<!-- 修改前 -->
+<Grid RowDefinitions="Auto,*,Auto">
+    <TextBlock /> <!-- 标题 -->
+    <Control Grid.Row="1" /> <!-- 内容 -->
+    <Border Grid.Row="2"> <!-- 底部栏 -->
+        <Button>关闭</Button>
+    </Border>
+</Grid>
+
+<!-- 修改后 -->
+<Grid RowDefinitions="Auto,*">
+    <Grid ColumnDefinitions="*,Auto"> <!-- 标题栏 -->
+        <TextBlock /> <!-- 标题 -->
+        <Button>×</Button> <!-- 关闭 -->
+    </Grid>
+    <Control Grid.Row="1" /> <!-- 内容 -->
+</Grid>
+```
+
+**优势**:
+- ✅ 减少嵌套层级
+- ✅ 更清晰的布局结构
+- ✅ 更现代的 UI 模式
+
+#### 2. FluentIcon 使用
+```xml
+<fi:FluentIcon Icon="Dismiss"
+               IconVariant="Regular"
+               FontSize="16" />
+```
+
+**优势**:
+- ✅ 符合 Fluent Design System
+- ✅ 更好的视觉一致性
+- ✅ 更小的内存占用
+- ✅ 更好的可扩展性
+
+---
+
+## 代码审查要点
+
+### 潜在问题
+
+#### 1. 用户交互变化 🟡
+```
+⚠️ 中风险: 移除了底部"关闭"按钮，用户需要使用标题栏的关闭按钮
+```
+
+**考虑因素**:
+- 用户可能习惯使用底部关闭按钮
+- 需要确保用户知道如何使用新的关闭按钮
+- 建议验证用户反馈
+
+#### 2. 可访问性问题 🟡
+```
+⚠️ 中风险: 需要确保关闭按钮有适当的键盘快捷键支持
+```
+
+**考虑因素**:
+- 通常窗口关闭对应 Escape 键
+- 需要验证焦点顺序
+- 确保屏幕阅读器可以识别
+
+#### 3. 触摸设备适配 🟡
+```
+⚠️ 中风险: 自定义关闭按钮尺寸较小（32x32），在触摸设备上可能需要增大
+```
+
+**考虑因素**:
+- 触摸目标应该至少 44x44 像素
+- 需要在不同尺寸的设备上测试
+
+### 优点
+
+- ✅ **现代设计**: 使用 FluentIcon，符合 Fluent Design System
+- ✅ **简化布局**: 移除多余的底部栏，界面更清爽
+- ✅ **文本优化**: "添加小组件"比"添加"更明确
+- ✅ **视觉一致性**: 水平居中对齐提升文本可读性
+- ✅ **代码质量**: XAML 结构清晰，变更明确
+
+### 建议
+
+- ⚠️ **测试建议**: 在不同屏幕尺寸下测试窗口布局
+- 📝 **文档建议**: 如果这是用户体验的重大变化，考虑更新相关文档
+- 🔍 **验证**: 确认 Escape 键等键盘快捷键仍然有效

+
+**变更说明**: 
+- 同样移除了 `if-else` 语句后的多余分号 `;`
+- 保持代码风格一致性
+
+---
+
+## 技术分析
+
+### Pascal Script 语法规范
+
+在 Inno Setup 的 Pascal Script 中，`if-then-else` 语句的语法要求：
+
+```pascal
+if condition then
+begin
+  // statements
+end  // ← 不应该有分号
+else
+begin
+  // statements
+end;  // ← 只有最后的 end 需要分号
+```
+
+**错误原因**: 
+- 在 Pascal 语言中，`else` 关键字不能与分号一起使用
+- 因为 `else` 是语句的一部分，不是独立的语句
+- 只有在 `if` 语句完全结束时才需要分号
+
+**影响范围**:
+- 虽然某些编译器可能容忍这种错误，但移除分号是正确的做法
+- 提高了代码的可移植性和规范性
+
+---
+
+## 代码审查要点
+
+### 潜在问题
+
+1. **编译兼容性**: 
+   - ✅ 低风险：移除多余分号不会导致编译错误
+   - ✅ 实际上修正了潜在的语法问题
+
+2. **全局一致性**: 
+   - ⚠️ 建议检查：其他类似的 `if-else` 语句是否也遵循相同的风格
+   - 建议在项目中进行一次代码风格扫描，确保一致性
+
+### 优点
