- download_cover() now writes folder.jpg instead of _cover_download{ext}
- PNG responses are converted to JPEG via PIL during download (avoids PNG
in the album directory entirely)
- find_local_cover() priority: folder > front > cover > album (folder.jpg
is now the canonical name for both downloaded and manually placed covers)

AI-powered per-album pipeline: scan → local hints → MusicBrainz/Discogs/Claude
resolve → cover art → interactive or auto review → tag write + rename + report.
All external dependencies optional; 17/17 unit tests passing.
