subwave: resolve duplicates after library additions unlocked new matches

User added several previously-recommended albums/compilations to the
library (AC/DC Ballbreaker, Rancid ...And Out Come the Wolves, Garbage,
Foo Fighters, Goo Goo Dolls, Melissa Etheridge x2, Big Shiny Tunes, MTV
Buzz Bin Vol. 2, etc.) and rescanned Navidrome. Re-running the matcher
across all 12 shows resolved many previous misses, which surfaced 6 new
cross-show duplicates (a song now matching in two shows at once). Each
was resolved by keeping the track on whichever show has its authentic/
better chart rank, matching the same policy used earlier this session.

Match counts after re-run: 1994 shows 13/29, 10/24, 10/27, 14/26; 1995
shows 22/30, 20/30, 19/30, 10/17; 1996 shows 17/35, 15/28, 19/29, 13/30.
