## 删除分屏功能 - 删除 ViewMode 'split' 类型，仅保留 editor/preview - 删除 splitRatio 状态和 Resizer 组件 - 删除滚动同步模块 (scrollSync.ts, rehypeSourceLine.ts) - 更新快捷键: Ctrl+1 编辑, Ctrl+2 预览 ## Bug 修复 - 修复 Toast setTimeout 内存泄漏 (App.tsx) - 修复 ModifiedBanner reload 更新错误标签 (改用 modifiedFilePath 匹配) - 修复 FileWatcher error 未重置 isSelfWriting (file-watcher.ts) - 修复另存为时未 stop watcher (ipc-handlers.ts) ## 死代码清理 (10 项) - 删除 main/ipc-channels.ts (与 shared/ 重复) - 删除 main/file-system.ts 未使用的 formatBytes - 删除 constants.ts 6 个未使用常量 - 删除 fileUtils.ts 未使用的 formatBytes - 删除 Icons.tsx 5 个未使用图标 (SplitView/ChevronUp/ChevronDown/X/ArrowUp/ArrowDown) - 删除 useCodeMirror 未使用的 getContent/scrollTo - 删除 TabBar 未使用的 menuRef - 删除 Tab.scrollLeft/previewScrollTop 字段 - 删除 tabStore 未使用的 getTabIndex - 删除 Toast/ModifiedBanner 多余 React import ## 安全加固 - ipc-handlers: 添加路径遍历防护 (validatePath 函数) - preload: openExternal 仅允许 http/https 协议 - window-manager: 启用 sandbox: true - preload: removeAllListeners 改为精确取消订阅 (返回 Unsubscribe 函数) ## 状态持久化 - activeTabId 持久化到 IndexedDB (刷新后恢复正确标签) - sidebar 状态持久化到 IndexedDB (isVisible/sidebarWidth) ## 代码优化 - preload 使用 IPC_CHANNELS 常量替代硬编码字符串 - ipc-handlers _event 类型改为 IpcMainInvokeEvent - settingsRepository 删除 splitRatio 字段
