feat(0.9): romaji sort-tags only, robust dupe detection, Mittelweg no-duration, autofill all fields

- Japanese tracks stored with original names in folder/filename/tags; romaji only in sort tags
- findExistingTrack: case-insensitive, searches all album folders under artist, strips release suffix
- --max-filesize 30M + 2x duration cap on all yt-dlp calls
- iTunes collectionArtistName captured as album_artist; fixes compilation album splitting
- album_artist tag uses mainArtist (not rawArtist) so all tracks in one album are consistent
- No-duration cascade: steps 5-8 (title-only/no-filter) removed — fail cleanly like with-duration
- Autofill iTunes: fills title, artist, albumArtist, discNum (was album/genre/year/track/total only)
- Autofill MusicBrainz: fills albumArtist, discNum (was missing both)
