Module cover 

Cover art fetcher: walks a library, finds album dirs without folder.jpg, queries MusicBrainz → CAA then iTunes as fallback, saves folder.jpg.

Network calls require --online (enforced by the CLI layer). Results are cached in $XDG_CACHE_HOME/dapctl/metadata/cover_cache.json with a 30-day TTL so repeated runs don’t hammer the APIs.
