// The sweeper's selection. An album qualifies when:

//   - it still has at least one track whose file has been missing longer than
//     the grace window. Measured on missing_since, which reconcile never
//     re-stamps (#2523), so it is a genuine "gone since" clock;
//   - MusicBrainz can name it: the album and its artist have MBIDs. Albums
//     failing this are counted separately (CountAlbumsMissingWithoutMbid);
//   - it is on the wanted list (#5567): an album taken off the list, or
//     dropped into the library by hand, is not fetched back;
//   - no want already covers it: none open, and none held since its files
//     went missing. A want held after the loss means the library has a full
//     copy despite the missing rows (#5245), so asking again would loop.
