前端更新内容：
1. FileTree.js
   - Ant Design Tree 组件集成
   - 文件状态标签显示（一致/冲突/本地更新/数据库更新）
   - 统计信息展示（总文件数、总大小、冲突数）
   - 刷新状态按钮
   - 文件选择事件处理

2. FileDiff.js
   - 丝滑的差异对比组件
   - 使用 diff 库计算行级差异
   - 颜色区分：绿色（新增）、红色（删除）
   - 显示变动行数标签
   - 支持大文件截断提示
   - 刷新按钮

3. package.json
   - 新增 diff 依赖（行级差异计算）
   - 新增 react-syntax-highlighter 依赖（代码高亮）

用户体验：
- 点选文件 → 自动加载差异
- 实时状态显示
- 一键同步按钮
- 流畅的动画效果

点选-对比-同步流程完整实现！
