- Bun's inotify-backed fs.watch permanently stops delivering events after
observing git's atomic HEAD.lock -> HEAD rename in the watched directory
(oven-sh/bun#24875), so the directory-watch fix for issue #8412 still froze
the status-line branch on Linux after the first switch; CI caught it as a
30s timeout in status-line-vcs-refresh.test.ts.
- Added git.head.watch: fs.watchFile stat-poll of the HEAD path (reftable dir
for reftable repos) with a disposer; path-based polling survives inode swaps
on every platform.
- Status line and footer now consume the helper; the footer previously bound
fs.watch to the HEAD file inode and died after one switch on all platforms.
- Dropped the FSWatcher error-listener plumbing (StatWatcher has no error
mode) and reworked the watcher lifecycle tests to the stat-poll contract;
verified the atomic-rename regression test passes on Linux bun 1.3.14 in
Docker where it previously timed out.
