Construct the tag SettingsService + Enricher at boot (mirroring coverart:
reconcile providers, bump the sources version if the provider set changed
to re-open settled rows), then run a standalone background Worker that
drains tracks needing folksonomy tags on a periodic tick.
Standalone (not threaded through the file-scan chain like cover art)
because tag lookups need only DB fields — recording MBID / artist / title
— so it mirrors the ListenBrainz similarity worker instead: an initial
drain shortly after boot, then every 30 min, up to 200 tracks per tick.
MusicBrainz's 1 req/s ceiling is the real throttle.
