bug

在 Windows 上开启工作区搜索（flashgrep）后，Agent 执行某些 shell 命令会随机报“另一个程序正在使用此文件 / 拒绝访问”（Windows 错误 32/5），例如：

flashgrep 以 flashgrep serve --stdio 单例常驻子进程运行，工作区一打开就被拉起，之后整个应用运行期间不退出。由此在 Windows 上产生持续的文件占用：

进程常驻：daemon 仅在应用退出（perform_process_exit_cleanup → shutdown_blocking，src/apps/desktop/src/lib.rs）或关闭“工作区搜索”功能时被停止；工作区打开即被 warmup 拉起（src/apps/desktop/src/api/workspace_activation.rs）。
索引放在工作区内：default_storage_root 返回 {repo}/.bitfun/search/flashgrep-index（src/crates/services/services-integrations/src/workspace_search/service.rs）。daemon 以 mmap / WAL / segment 方式持有这些索引文件（协议字段 active_segments / active_delete_segments / pending_docs 佐证）。
空闲释放形同虚设：schedule_repo_release 只在“warmup 后工作区已切走”的竞态分支被调用一次，正常 search/glob/status 流程从不触发；且 release_repo_if_idle 只发送 CloseRepo，不停止 daemon 进程。

在 Windows 上，进程句柄 / 内存映射 / 目录监听句柄会阻止文件被删除、重命名或覆盖，因此 daemon 存活期间索引文件（以及 flashgrep.exe 映像）一直处于被占用状态。

空闲时真正释放 repo 会话，并在会话清空后停止 daemon 进程（复用已有的透明重启能力）。
把索引移出工作区，放入全局 ~/.bitfun/projects/<workspace-slug>/ 目录（已有 sessions / snapshots / plans 等按工作区分片的持久化目录）。
反馈 / 升级上游 wgqqqqq/flashgrep（当前 v0.2.10），确认 Windows 下是否以 FILE_SHARE_DELETE 打开文件、CloseRepo 是否解除 mmap。
