The watcher's localized reindex was non-recursive and only ever touched the
exact folders it was handed, so renaming/moving a *container* dir (an artist
folder, or a whole subtree) left the manifest inconsistent: the renamed-in
album children were never indexed, and the old path's album keys lingered
forever (only the nightly full reindex healed it).
reindexFolder now takes { recursive } and, for any folder, also prunes any
manifest descendant whose top-level child dir has vanished from disk. The
watcher enqueues the containing folder SHALLOW (rebuild-this-album + prune a
renamed/removed-away child) and the event path itself RECURSIVE (index a
new/renamed-in container's album children). A recursive reindex of a plain
file or leaf album stays a cheap no-op / single rebuild, and a shallow reindex
of a big container (e.g. Albums) is just a readdir + key scan — no deep walk.
Verified in an isolated temp library: a case-only artist rename prunes the old
keys and indexes the 3 renamed albums while leaving unrelated albums alone; a
leaf file edit rebuilds just that album; deleting an album folder prunes it.

Extract walk()'s per-folder logic into a reusable buildFolder(), so a single
album/artist can be (re)indexed on its own. Add:
- reindexFolder(rel): rebuild just one folder's live cache entry + patch the
manifest (prune if the folder vanished). Its mtime-based signature means any
change — add / re-tag / delete — is picked up, and irrelevant touches no-op.
- withIndexLock: serialize ALL index mutations (full / incremental / localized)
so a localized reindex can never race the full reindex's atomic swap.
- watcher.ts: fs.watch(~/Music, { recursive }) → log every change → debounce 3s →
reindexFolder the affected folder(s). Verified: Bun's recursive watch fires
through the ~/Music symlink and on new-dir creation (so a new album's contents
are read by reindexFolder); inotify max_user_watches (~483k) >> folder count.
Started at boot, stopped on shutdown. The nightly full reindex backstops any
change that lands after a new folder's debounce.
