Reopening an artist (discography), an album (tracklist), or repeating a lookup
re-hit MusicBrainz every time with no cache and no throttle. Adds a generic
Postgres-backed read-through cache keyed on the LOGICAL operation (not the
request URL) so the worker and web app share entries.
- New ApiCache(key, json, fetchedAt) model + migration (generic name so the
Last.fm browse cache can ride the same table).
- lib/apicache.ts cached(): read-through, TTL from fetchedAt (tunable, no
migration), serve-stale-on-outage, never caches null.
- Wrap the high-level MB fns with logical keys + TTLs: discography &
tracklists & artist-name 30d, searchReleaseGroup 7d, searchArtists 1d.
Search keys normalized (trim+lowercase) to match the worker byte-for-byte.
- album-modal: a session-scoped Map<rgMbid,Track[]> so reopening is instant
with zero network (complements the DB cache).
- Test setup clears ApiCache between tests. web 147 tests, tsc + build clean.

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.

searchReleaseGroup took the first MusicBrainz hit, so a title MB ranks with the
single first (e.g. "Thriller" ties single+album at score 100) resolved to the
single — the Last.fm album modal and the Want flow then showed a 1-track single.
Prefer a clean Album > EP > Single > album-with-secondary, keeping MB order as the
in-tier tiebreak; single-only titles still resolve.

A `"` or `\` inside artist/album terminates the quoted Lucene phrase
and corrupts the MusicBrainz search query. Escape both terms before
interpolation.
