refactor: 架构重构 - 解耦过度耦合模块
主要改动: 1. 创建乐观更新工具函数 (optimisticUpdate.ts) - 消除 userStore.ts 中的重复代码 2. 拆分 useResponsive.ts (485行 -> 12个专注模块) - useBreakpoint: 断点检测 - useOrientation: 方向检测 - usePlatform: 平台检测 - useScreenSize: 屏幕尺寸 - useResponsiveValue: 响应式值 - useResponsiveStyle: 响应式样式 - useMediaQuery: 媒体查询 - useColumnCount: 列数计算 - useResponsiveSpacing: 响应式间距 3. 整理数据层 (Repository 层) - ApiDataSource: API数据源 - LocalDataSource: 本地数据源 - CacheDataSource: 缓存数据源 - MessageRepository: 消息仓库 4. 重构 messageManager.ts (2194行 -> 4个模块) - MessageStateManager: 状态管理 - WebSocketMessageHandler: WebSocket处理 - MessageSyncService: 消息同步 - ReadReceiptManager: 已读管理 5. 导航解耦 (MainNavigator.tsx: 1118行 -> 100行) - 创建 NavigationService 解耦层 - 拆分多个 Navigator 组件 架构改进: - 单一职责原则: 每个模块职责明确 - 依赖倒置: 通过接口解耦 - 代码复用: 工具函数可被多处使用 - 可测试性: 各模块可独立测试
