twislaandClaude Opus 5.5 5878adb756 Let a tag play several albums in order
An assignment is now an ordered list of albums (e.g. one vinyl compiling two EPs that are separate releases in the library). Albums move to their own table, with a migration for existing databases. The scan and lookup responses return an albums list instead of the single artist/album/uri fields. The tag page lists its albums with up, down and remove, and search results get an Add button.
