Fix JamAlt task class naming to match metadata names

Renamed classes to match their metadata names so they can be found in the task registry:
- JamAltArtist → JamAltArtistA2ARetrieval
- JamAltLyricsT2A → JamAltLyricT2ARetrieval
- JamAltLyricsA2T → JamAltLyricA2TRetrieval

Also added explicit imports and exports for proper registration.
