Finder moves files to Trash (rename) instead of deleting them, which may be reported as `Modify(Name)` rather than `Remove` by the file watcher. This caused untracked files to lose their red color without being removed from the tree. Fix by checking disk existence in the event batch emitter and promoting the kind to "remove" when a changed path no longer exists. Co-Authored-By: Claude Opus 4.6 (1M context) <noreply@anthropic.com>
