Phase 2完成：Tauri管理工具开发 + Phase 1双虚拟目录实现

Phase 1成果：
- 数据库准备：demo.sqlite（117文件，5.07GB）
- 双虚拟Tree：demo_library_zh + demo_library_en
- 文件分类映射：258个节点（自动分类）

Phase 2成果：
- Tauri项目初始化：完整项目结构
- 7个管理模块：安装/配置/诊断/管理/健康/监控/文件浏览
- 7个Rust Commands：完整后端逻辑（约3000行）
- 7个Vue页面：完整前端UI（约2000行）
- Vite build修复：Rolldown外部化配置成功
- 前端构建成功：dist目录生成

总体进度：90%完成（约5000行代码）
