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.

+## 影响分析
+- 受影响的模块: LanMountainDesktop, Views, ViewModels
+- 涉及 28 个 C# 文件变更
+- 涉及 UI/XAML 文件变更
+- 这是一个功能新增提交，扩展了项目能力
+
+## 代码审查要点
+- ⚠️ 关键文件变更: MainWindow - 需要特别关注
+- ⚠️ 设置窗口是核心功能，需要确保用户体验
+
+## 详细分析
+
+### 1. Fluent Shell 设计
+设置窗口采用了 Fluent Design System 的设计语言：
+
+- **导航面板**: 左侧导航采用 Fluent 风格的图标和布局
+- **内容区域**: 右侧内容区采用卡片式布局
+- **动画效果**: 添加了流畅的过渡动画
+
+### 2. 搜索功能
+新增了设置搜索功能：
+
+- **实时搜索**: 输入时即时显示搜索结果
+- **高亮显示**: 匹配的关键词会被高亮
+- **快捷导航**: 点击搜索结果直接跳转到对应设置项
+
+### 3. 技术实现
+```csharp
+public class SettingsSearchService
+{
+    public List<SearchResult> Search(string query)
+    {
+        // 搜索所有设置项
+        // 返回匹配的结果
+    }
+}
+
+public class FluentSettingsShellViewModel
+{
+    public ObservableCollection<SettingsCategory> Categories { get; }
+    public SettingsSearchService SearchService { get; }
+}
+```
+
+### 4. 用户体验改进
+- 更直观的设置分类
+- 更快的设置查找
+- 更美观的界面设计
+
+## 建议
+1. 添加搜索历史功能
+2. 考虑添加设置项的快捷键
+3. 优化搜索性能
+4. 收集用户反馈持续改进
