fix: playlist cover art, compilation tag, and year

- ripPlaylist/ripTrackCollection: pre-fetch playlist artwork once, embed in all tracks
- ripTrack: skip per-track album cover when playlist embed is provided
- buildTagMetadata: set COMPILATION=1 and year from playlist publish_date
- beatport: normalize playlistMetadata to include date fields for year extraction
- qobuz: normalize playlist image_rectangle to standard image map
