新增：文件系统导航面包屑

功能：
- 新增 PathBreadcrumb 组件，支持路径快速跳转
- 新增 DropdownItem 通用下拉菜单组件

优化：
- 版本升级流程优化（Pinia 状态管理、进度节流、完整下载验证）
- 模块延迟初始化（数据库、文件系统按需启动）
- API 数据格式统一（蛇形转驼峰）
- CodeMirror 语言包按需动态加载
- Markdown 渲染增强（支持锚点跳转）

重构：
- 迁移到 Pinia 状态管理（stores/config.ts、stores/theme.ts、stores/update.ts）
- 简化 UpdatePanel、UpdateNotification、ThemeToggle 逻辑
- 优化表结构加载逻辑

清理：
- 删除测试组件 index-simple.vue
- 删除旧的 useTheme.ts
