Watch git status updates

[rabanspiegel]

Summary

• add git status watchers (with polling fallback) and debounce broadcast
• cache git status results in the renderer to avoid duplicate requests
• skip background refresh while the document is hidden

Context

Clean extraction of the git status watcher/caching change from #740. Thanks @cschubiner.

Testing

• not run

Note

Medium Risk
Introduces new filesystem watching + broadcast logic and changes how git status is refreshed/cached in the renderer, which could cause missed/extra refreshes or watcher leaks on some platforms.

Overview
Adds a main-process git status watcher (git:watch-status/git:unwatch-status) that uses recursive fs.watch (macOS/Windows only), debounces events, and broadcasts git:status-changed to all windows with basic error recovery.

Updates the renderer to consume these status-change events in useFileChanges and useTaskChanges, forcing refreshes when changes are detected while skipping background refresh when the document is hidden/unfocused. Introduces a 30s renderer-side getCachedGitStatus cache with in-flight de-duping to reduce repeated git:get-status IPC calls, and extends preload/global Electron API typings for the new watch/unwatch/event APIs.
