The task strip's "Output" button opens the task log through openFilePreview, but the log lives under the OS temp root, outside every notify-watched workspace root, so the open-tab watcher never sees it change. A null-rendering leaf component now polls the active, clean output tab every 2 s while its task is live and routes changes through applyExternalReload; the interval stops as soon as the task settles, the tab closes, or the buffer turns dirty.

背景
聊天窗口顶部后台任务提醒条的"输出"按钮通过 openFilePreview 打开任务日志。日志位于系统临时目录，在所有已注册工作区根目录之外，后端文件监听覆盖不到这个文件，标签页打开后内容不再更新。已有的激活时新鲜度检查只在切换标签页的那一刻运行，用户停留在日志标签页期间看不到新内容。
改动
新增组件 LiveOutputFileWatcher，挂在 conversation-shell.tsx 的 AsyncTaskStrip 旁边，自身不渲染任何内容。以下三个条件同时满足时，它每 2 秒比对一次激活标签页的 etag 与磁盘：
etag 变化时走工作区存储的 applyExternalReload 写入新内容，复用它的代数检查、拒绝覆盖未保存内容、git 基线刷新。读取失败（最常见是日志被清理）时走 rejectFileTab 把错误显示在标签页上。任务结束、标签页关闭或用户开始编辑后，轮询定时器随之拆除。
组件是独立叶子节点：对高频 fileTabs 切片的订阅只触发这个空渲染组件重渲染，不影响会话外壳的渲染路径。
验证
取舍
没有改用文件系统监听：后端现有 notify 监听器有已知的事件丢失问题（src-tauri/src/workspace_state/mod.rs:1590 注释记载 macOS FSEvents 会丢事件），即使加监听也需要轮询兜底；现有 2 秒轮询已有任务存活、标签页激活、无未保存修改三重控制，空闲时成本接近零。
