searchReleaseGroup used a strict exact-phrase releasegroup:"<album>", so
Last.fm album names with per-release edition/version qualifiers ("The Stranger
(Legacy Edition)", "Nevermind - Remastered") returned 0 hits → 404 → "No
MusicBrainz match", even though MB knows the artist and the base title.
Add stripEditionQualifiers (removes a trailing edition parenthetical/bracket or
" - " suffix only when it names an edition — deluxe/remaster/legacy/edition/…,
never a plain title parenthetical) and search in decreasing precision: exact
phrase on the given title → exact phrase on the stripped title → a loose
unquoted fallback. Clean titles still resolve in one request; albumPreferenceRank
ranking unchanged. Fixes both callers (/api/mb/release-group + /api/wanted).
Verified live against real MB: "The Stranger (Legacy Edition)"→The Stranger,
"Nevermind - Remastered"→Nevermind, Continuum unchanged. web 141 tests.
