Support .laapp/plugin.json and improve market models

Add support for the new plugin package contract (.laapp + plugin.json) while keeping backward compatibility with legacy .lmdp/manifest.json, and improve market metadata resolution and launcher handling. Key changes: - LanMountainDesktop.Launcher: PluginInstallerService now recognizes plugin.json and .laapp, preserves legacy manifest/package names, searches for manifests with a helper, and removes existing packages matching either extension. - LanMountainDesktop.PluginTemplate: README updated to document .laapp, plugin.json, runtime contract and packaging expectations. - Tests: New and extended tests for PluginInstallerService and a PluginMarketIndexDocumentTests covering nested index parsing and metadata enrichment. - LauncherClient & PluginMarketInstallService: ResolveLauncherPath now probes multiple candidate locations (useful for dev and packaged layouts); LauncherClient also adjusted launcher arguments to use the updated CLI form. - SettingsDomainServices: Added BuildCapabilities to safely build capability lists from entries (null checks, projection, de-dup via DistinctBy). - AirAppMarketMetadataResolverService & PluginMarketModels: Prefer existing manifest/publication/compatibility values when enriching entries, add ApiVersion/Path fields, normalize compatibility logic and package source URL/path handling; handle Sha256/size/publication dates more robustly. - Misc: Added localization spec/checklist/tasks under .trae for a localization fix initiative. These changes enable the new plugin packaging format, improve robustness of market data enrichment, make launcher discovery more flexible for different environments, and add tests and docs to cover the new behaviors.
Introduce render mode & static component previews

+# Avalonia 12 Full Stack Migration
+
+## Summary
+
+LanMountainDesktop has moved its desktop stack to the Avalonia 12 baseline. The migration covers the main host, Launcher, Plugin SDK, plugin runtime loading policy, official WebView usage, ClassIsland Markdown, FluentAvalonia, FluentIcons, and Material-related dependencies.
+
+## Requirements
+
+### Requirement: Centralized Avalonia 12 dependency baseline
+
+The solution SHALL use central package management for direct Avalonia-facing projects and keep the core UI dependency baseline on Avalonia `12.0.1`.
+
+Required package baseline:
+
+- `Avalonia*` `12.0.1`
+- `Avalonia.Controls.WebView` `12.0.0`
+- `ClassIsland.Markdown.Avalonia` `12.0.0`
+- `FluentAvaloniaUI` `3.0.0-preview1`
+- `FluentIcons.Avalonia` `2.1.325`
+- `Material.Avalonia` `3.16.0`
+- `Material.Icons.Avalonia` `3.0.2`
+
+### Requirement: Official WebView
+
+The host SHALL use `Avalonia.Controls.NativeWebView` for the browser widget and SHALL NOT reference `WebView.Avalonia`, `AvaloniaWebView`, or `.UseDesktopWebView()`.
+
+Windows WebView2 user data configuration SHALL be supplied through `EnvironmentRequested` using `WindowsWebView2EnvironmentRequestedEventArgs.UserDataFolder`.
+
+### Requirement: Plugin SDK v5
+
+The Plugin SDK API baseline SHALL be `5.0.0`. SDK v4 plugins are treated as incompatible until rebuilt.
+
+The SDK SHALL keep the existing public UI extension shape, including `SettingsPageBase` and Avalonia `Control` based desktop components.
+
+### Requirement: Launcher data location stability
+
+Launcher data location configuration SHALL be read from a fixed bootstrap Launcher data directory so resolving the selected data root cannot recursively require resolving itself.
+
+### Requirement: OOBE state compatibility
+
+The Launcher SHALL read current OOBE state from the resolved `Launcher/state` directory and SHALL continue to migrate the legacy `.launcher/state/first_run_completed` marker.
+
+## Acceptance
+
+- `dotnet build LanMountainDesktop.slnx -c Debug` completes with 0 errors.
+- `OobeStateServiceTests` pass.
+- Full `dotnet test LanMountainDesktop.slnx -c Debug` no longer aborts from `DataLocationResolver` recursion.
+- Plugin template defaults to SDK package version `5.0.0` and manifest `apiVersion` `5.0.0`.
+- Current developer documentation points to SDK v5 and Avalonia 12.

+# 本地化修复 Spec
+
+## Why
+
+- 项目在中文设置下，多处 UI 仍显示英文。
+- 主要问题集中在：
+  1. `MainWindow.axaml` 中任务栏头像弹窗、电源菜单、组件库等文本硬编码为英文，且未被 `ApplyLocalization()` 覆盖。
+  2. `LanMountainDesktop.Launcher` 的所有视图完全没有接入本地化系统。
+  3. 部分组件（BrowserWidget、WhiteboardWidget、HolidayCalendarWidget 等）存在未覆盖的硬编码英文。
+  4. 少量设置页面 Tooltip 硬编码英文。
+
+## What Changes
+
+### 1. MainWindow.axaml 硬编码修复
+将以下硬编码文本改为由 `ApplyLocalization()` 通过 `L()` 动态设置：
+- 任务栏头像弹窗：`User` → `power.user` / `Settings` → `settings.title` / `Edit Desktop` → `button.component_library` / `Power` → `power.title`
+- 电源菜单：`Back` → `common.back` / `Power` → `power.title` / `Shutdown` → `power.shutdown` / `Restart` → `power.restart` / `Log Out` → `power.logout` / `Sleep` → `power.sleep` / `Lock Screen` → `power.lock_screen`
+- 组件库：`Widgets` → `component_library.title` / `Back` → `common.back` / `No components.` → `component_library.empty`
+- 悬浮芯片：`Widgets` → `component_library.title`
+
+### 2. Launcher 视图本地化
+为 `LanMountainDesktop.Launcher/Views/` 下的窗口引入独立本地化机制（复用 `LocalizationService` 或内嵌资源字典）：
+- `SplashWindow.axaml`：`LanMountain Desktop`、`Initializing...`
+- `DataLocationPromptWindow.axaml`：全部文本
+- `ErrorWindow.axaml`：全部文本
+- `LoadingDetailsWindow.axaml`：全部文本
+- `UpdateWindow.axaml`：`Update`
+
+### 3. 组件硬编码修复
+- `BrowserWidget.axaml`：`Browser runtime unavailable.` → 新增键 `browser.widget.unavailable`
+- `WhiteboardWidget.axaml`：`Pen` / `Eraser` / `Clear` / `Export SVG` → 新增键 `whiteboard.tool.pen` 等
+- `HolidayCalendarWidget.axaml`：`Holiday countdown` / `Days` → 新增键 `holiday.widget.title` / `holiday.widget.days`
+- `BilibiliHotSearchWidget.axaml`：`Trending Topic` → 新增键 `bilihot.widget.trending_topic`
+- `WallpaperSettingsPage.axaml`：`Custom color` Tooltip → 复用 `settings.wallpaper.custom_color_tooltip`
+
+### 4. 本地化资源文件补充
+在 `zh-CN.json` 和 `en-US.json` 中补充上述新增键值。
+
+## Impact
+
+- Affected code:
+  - `LanMountainDesktop/Views/MainWindow.axaml`
+  - `LanMountainDesktop/Views/MainWindow.SettingsHardCut.Stubs.cs`
+  - `LanMountainDesktop.Launcher/Views/*.axaml`（多个文件）
+  - `LanMountainDesktop/Views/Components/BrowserWidget.axaml`
+  - `LanMountainDesktop/Views/Components/WhiteboardWidget.axaml`
+  - `LanMountainDesktop/Views/Components/HolidayCalendarWidget.axaml`
+  - `LanMountainDesktop/Views/Components/BilibiliHotSearchWidget.axaml`
+  - `LanMountainDesktop/Views/SettingsPages/WallpaperSettingsPage.axaml`
+  - `LanMountainDesktop/Localization/zh-CN.json`
+  - `LanMountainDesktop/Localization/en-US.json`
+- Affected behavior:
+  - 中文设置下上述位置将正确显示中文。
+  - Launcher 各窗口将支持中英文切换。
+
+---
+
+## Requirements
+
+### Requirement: MainWindow 任务栏弹窗与电源菜单本地化
+系统 SHALL 在 `ApplyLocalization()` 中覆盖任务栏头像弹窗和电源菜单的所有文本。
+
+#### Scenario: 中文设置下打开任务栏弹窗
+- **WHEN** 语言设置为中文
+- **THEN** 弹窗中显示"设置"、"桌面编辑"、"电源"等中文文本
+- **AND THEN** 电源菜单中显示"返回"、"关机"、"重启"、"注销"、"睡眠"、"锁定屏幕"等中文文本
+
+### Requirement: Launcher 窗口本地化
+系统 SHALL 让 Launcher 的所有窗口文本通过本地化服务获取。
+
+#### Scenario: 中文设置下启动应用

 The generated project references `LanMountainDesktop.PluginSdk` and produces a `.laapp` package automatically when built.
+
+## Package contract
+
+Every plugin package must contain:
+
+- `plugin.json`
+- the entrance assembly declared by `entranceAssembly`
+- the `.deps.json` next to the entrance assembly
+
+Optional package content:
+
+- `Localization/*.json`
+- plugin assets and other managed dependencies
+- `airappmarket-entry.template.json` in the repository root for market publishing
+
+Market publishing uses `market-manifest.json` with `schemaVersion`, `manifest`, `compatibility`, `repository`, `publication.packageSources`, and `capabilities`.

Author	SHA1	Message	Date
lincube	fc4d0c4cd8	Support .laapp/plugin.json and improve market models Add support for the new plugin package contract (.laapp + plugin.json) while keeping backward compatibility with legacy .lmdp/manifest.json, and improve market metadata resolution and launcher handling. Key changes: - LanMountainDesktop.Launcher: PluginInstallerService now recognizes plugin.json and .laapp, preserves legacy manifest/package names, searches for manifests with a helper, and removes existing packages matching either extension. - LanMountainDesktop.PluginTemplate: README updated to document .laapp, plugin.json, runtime contract and packaging expectations. - Tests: New and extended tests for PluginInstallerService and a PluginMarketIndexDocumentTests covering nested index parsing and metadata enrichment. - LauncherClient & PluginMarketInstallService: ResolveLauncherPath now probes multiple candidate locations (useful for dev and packaged layouts); LauncherClient also adjusted launcher arguments to use the updated CLI form. - SettingsDomainServices: Added BuildCapabilities to safely build capability lists from entries (null checks, projection, de-dup via DistinctBy). - AirAppMarketMetadataResolverService & PluginMarketModels: Prefer existing manifest/publication/compatibility values when enriching entries, add ApiVersion/Path fields, normalize compatibility logic and package source URL/path handling; handle Sha256/size/publication dates more robustly. - Misc: Added localization spec/checklist/tasks under .trae for a localization fix initiative. These changes enable the new plugin packaging format, improve robustness of market data enrichment, make launcher discovery more flexible for different environments, and add tests and docs to cover the new behaviors.	2026-04-30 00:02:52 +08:00
lincube	eb066b53f1	Introduce render mode & static component previews Add DesktopComponentRenderMode and thread the render mode through runtime context and creation APIs so controls can be created for library previews. Replace image-based preview system with static preview Controls: viewmodels and ComponentLibraryWindow now use PreviewControl, and ComponentPreviewImageService/related types and tests were removed. Add ComponentPreviewRuntimeQuiescer to attach/detach preview controls (stop timers, disable input) for safe static previews. Simplify component-library collapse state/presenter by removing transient expanded opacity handling. Update runtime registry, services, views and tests to support the new flow.	2026-04-29 19:43:29 +08:00
lincube	5ea242af9a	Lock swipe handling to initiating pointer Track the pointer id that starts a swipe and restrict subsequent pointer events to that id. Added nullable _desktopSwipePointerId and _swipePointerId fields, IsDesktopSwipePointer/IsSwipePointer helpers, and set/cleared the ids at swipe start/end. Guard pointer moved/released/capture-lost handlers to ignore other pointers and avoid unintended cancellation or interference from additional touches or mouse input. Changes in MainWindow.DesktopPaging.cs and TransparentOverlayWindow.axaml.cs improve multi-pointer robustness for desktop paging and overlay swipe interactions.	2026-04-29 17:25:51 +08:00
lincube	abfa64b3d7	Avalonia12 (#7 ) * ava12升级 * Enable centralized package versioning Add <Project> and <PropertyGroup> with <ManagePackageVersionsCentrally>true</ManagePackageVersionsCentrally> to Directory.Packages.props to enable centralized package version management across the repository. This allows package versions to be controlled from this single file instead of individual project files. * Migrate codebase to Avalonia 12 APIs Apply Avalonia 12 migration changes: replace SystemDecorations with WindowDecorations and remove ExtendClientAreaChromeHints/ExtendClientAreaTitleBarHeightHint usages; update BindingPlugins removal logic (no-op); switch clipboard usage to ClipboardExtensions.SetTextAsync; update Bitmap.CopyPixels calls to the new signature. Replace TextBox.Watermark with PlaceholderText, convert NumberBox styles to FANumberBox and adjust templates, change Checked/Unchecked handlers to IsCheckedChanged, and adapt FluentIcons usages (SymbolIconSource -> FASymbol/FAFont/FluentIcon equivalents). Fix MainWindow partial classes to inherit Window and correct missing variables/fields/usings. Add migration docs/specs/tasks under .trae and include a small TestFluentIcons project for icon testing. * Migrate to Avalonia 12 and Plugin SDK v5 Upgrade project to the Avalonia 12 baseline and Plugin SDK v5: centralize Avalonia packages, remove legacy WebView.Avalonia usage (use NativeWebView/WebView2 EnvironmentRequested), and update Fluent/Material icon/package usages. Bump multiple package/project versions to 5.0.0 and Avalonia 12.0.1, update plugin template and README/docs to SDK v5, and add PLUGIN_SDK_V5_MIGRATION.md. Also fix runtime/behavior bugs: make DataLocationResolver use a fixed bootstrap launcher data path and avoid recursive ResolveDataRoot; add legacy-state handling and extraction in OobeStateService; and update component settings tests to reflect migrated storage (DB/backup) and reset cache for test reloads. Various csproj, tests, and docs updated to reflect the migration and ensure build/test compatibility. * Update icon glyphs and symbol mappings Replace and refine icon sources across settings pages and controls: many FAFontIconSource glyphs were updated to specific Seagull Fluent Icons codepoints, some FASymbolIconSource usages were replaced with FAFontIconSource, and a number of symbol-to-Symbol enum mappings were adjusted (e.g. "Bell" -> AlertOn, "Shield" -> ShieldLock). Also clarified a comment in SettingsWindow and fixed a trailing newline in StudySettingsPage. Changes standardize icon visuals and bridge FluentIcons glyphs into FluentAvalonia icon sources. * fix.修复合并产生的问题。	2026-04-29 12:14:29 +08:00
