Fixes an infinite git-rescan loop on Windows introduced by #59876. On Windows, creating or deleting a file directly inside .git updates the directory's last-write time, so ReadDirectoryChangesW reports a bare .git Changed event alongside the file's own event. Since #59876, bare .git events schedule a git rescan (to cope with coalesced FSEvents on macOS), so every filtered-out lock-file event still triggered a rescan through its paired bare event. Because a rescan's own `git diff --numstat HEAD` can take .git/index.lock (even under --no-optional-locks, e.g. in jj-colocated repos whose index never refreshes clean), each rescan re-triggered the next one, spawning ~9 git processes per cycle, ~4 cycles/sec, indefinitely. Bare .git events are now deferred while processing an event batch and only trigger a rescan when the batch contains no filtered event for the same git dir that explains the directory change. A standalone bare .git event (the macOS coalescing case #59876 addressed) still triggers a rescan, as does any batch containing a meaningful .git change.
