perf: 全局响应速度优化——1.核心: 所有组件 useStore() 改为窄选择器 useStore(s=>s.field), 之前每次按键 setBody 改变 store.body 导致订阅整个 store 的 14 个组件全部 re-render(TiptapEditor/Editor/FileTree/TabBar/DocInfoPanel/Toolbar/App/SearchBox/TagFilter/SettingsPanel/GraphView/LinkGraph/MoreActions/TitleBar); TiptapEditor 不再订阅 body(仅 currentPath/setBody), body 从 getState() 在 effect 内获取; 2.OutlinePanel collect debounce 300ms(之前每次按键遍历文档树); 3.OutlinePanel scroll handler rAF 节流(之前每像素滚动调 coordsAtPos); 4.修复 TabBar resetEditor 重复声明 + TiptapEditor content 引用
