arookieofc 8d909598d5 fix(vfs): warn when the inotify watch limit leaves folders unwatched (#1918)
* fix(vfs): warn when the inotify watch limit leaves folders unwatched

When watch() hits the OS watch limit mid-tree (inotify ENOSPC/EMFILE), the affected directories were silently never watched: the project stayed stale with no hint. Record the failure on DirState and surface it through the new Watcher::unwatched_reason() — the host emits the 'sync may be slow' warning once the project opens and once on the first event batch after a late failure (deferred walk / update_watches).

Fixes #1915

* fix(vfs): latch the startup watch-limit warning so batches don't repeat it
