MusicBrainz search returns release-groups tied on title similarity in an
arbitrary order; `max(groups, key=_ratio)` kept the first, so Michael
Jackson's "Off the Wall" resolved to the 2-track *single* release-group
(Off the Wall / Get on the Floor) instead of the 10-track album. Because
plan_track_names labels files purely by position, that short tracklist got
mapped onto the full album — track 2 became "Get on the Floor" instead of
"Rock with You", and the real "Off the Wall"/"Get on the Floor" files kept
their streamrip names, yielding duplicate titles.
Extract selection into a pure `_best_release_group()` that breaks title-
similarity ties toward primary-type == "Album". Similarity still dominates;
album preference only settles ties. Live-verified: Off the Wall now resolves
to the 10-track album with track 2 = "Rock With You".
