kurihada fea5442d53 feat(ui): 添加文件 Diff 查看功能
当 AI 执行 write_file 或 edit_file 工具时,在工具结果中显示 View Diff 按钮,
点击后在 IDE 面板中显示文件修改前后的对比视图。

主要改动:
- core: edit_file/write_file 工具返回 fileDiff 元数据
- ui: 新增 DiffEditor 组件用于显示文件差异
- ui: ChatMessage 添加 View Diff 按钮
- ui: IDE 组件支持 Diff 视图切换
- ui: useChat hook 处理 fileDiff 回调
