library: MusicBrainz text matching + Match-Review UI (P8) (#710)
* library: MusicBrainz text matching + Match-Review UI — P8

Replaces the enrichment plumbing's no-op matcher (P7) with the real
pipeline, per the library-metadata design: a wrong match is worse than a
slow one, so medium confidence goes to a human review queue and never
straight to canonical values.

- lib/mb_match.py (new, pure — no network/DB/server imports): denoise
  (author credits, (440Hz)/(Live)/(No Lead)/(v2) parentheticals,
  diacritics/punctuation, ACDC / AC DC / AC/DC folding via compacted
  token equality), token-set similarity, scoring with year/duration
  corroboration bonuses, tier classification (auto needs combined
  >= 0.95 AND per-field floors — a perfect-title cover by the wrong
  artist, or a chart with no artist, can never auto-match), Lucene
  query building, MusicBrainz response normalization.
- Matcher precedence in _enrich_one: content-hash cache copy (another
  chart of the same recording matches with no network) -> manifest
  mbid (tier 0) / isrc (tier 1) exact keys, feature-detected and
  strictly shape-validated, read-only -> text search tiers
  (auto / review / failed).
- Lifecycle: review rows store their ranked candidate list (JSON) and
  write NO canonical fields until a human accepts; failed rows retry on
  an exponential backoff (1 h doubling, 7 d cap) via the attempts
  column; user-rejected rows never auto-retry; an identity edit
  re-queues anything and resets the backoff; never-overwrite-manual is
  enforced inside the single writer (apply_enrichment_match) so no call
  path can forget it.
- Network: _mb_http_get is the one transport seam — throttled to
  <= 1 req/s through P7's _enrich_throttle, identified with a real
  User-Agent from VERSION, and a 503 pauses the whole pass without
  burning attempts. Offline guard: no sockets under
  FEEDBACK_ENRICH_OFFLINE or FEEDBACK_SKIP_STARTUP_TASKS, so pytest can
  never reach MusicBrainz; the pass still stamps identity hashes
  (two-phase), which is why every P7 test passes unchanged.
- Routes: GET /api/enrichment/review, POST
  /api/enrichment/review/{filename}/accept|reject|pick, GET
  /api/enrichment/search (throttled manual-search proxy). All four are
  demo-mode blocked.
- Match facet: match= CSV accepted by /api/library AND
  /api/library/stats (the A-Z rail's letter counts stay lockstep with
  the grid) — review / matched (incl. manual) / unmatched / pending,
  the same EXISTS idiom as the mastery facet.
- UI: static/v3/match-review.js (new, self-contained) — an ambient
  "N to review" chip beside the song count (rendered only when
  non-zero; silent on success, no toasts), and a review drawer on the
  filter-drawer slide idiom (Escape + focus trap; row click accepts,
  "Not a match" rejects, "Search instead" is the fix-match escape
  hatch). songs.js gets the chip mount, a Match filter section, and
  session-only match state; also fixes the latent applySavedPrefs bug
  where restored filters dropped the mastery key, which made the
  filter drawer throw for anyone with saved prefs.
- static/tailwind.min.css regenerated (scripts/build-tailwind.sh) for
  the new utility classes; conflicts with sibling PRs resolve by
  re-running the script.

Nothing is ever written to pack files — canonical values live only in
the song_enrichment display cache. Cover art caching and acoustic
fingerprinting are follow-up slices.

22 pure unit tests + 19 server tests (fake transport injected over the
_mb_http_get seam) + demo-mode route cases; full-suite failure set
A/B-identical with the change stashed vs applied.

* library: match-review modal + configurable auto-apply confidence (P8 R0)

Follow-up to the initial P8 commit, folding in the first round of tester
feedback on the review surface and the matcher's knobs:

- Review GUI is a centred MODAL now, not a sidebar — one chart at a
  time (the scraper-review model from media-server / emulation-frontend
  apps): the chart's current metadata with explicit amber
  "Missing: album / year / cover art" chips (art detected via the art
  request failing), candidates each carrying "Adds: year - genres -
  ISRC" / "Shows as: ACDC -> AC/DC" per-field chips, and Skip /
  Not a match / Search instead / Use selected with prev-next + arrow-key
  navigation. Chip + window API surface unchanged, so songs.js needed no
  edits for the rework.
- Auto-apply confidence is a SETTING: default drops 0.95 -> 0.90
  (mb_match.AUTO_MIN; classify() takes an auto_min override). The
  per-field floors are untouched and threshold-independent — a
  perfect-title cover by the wrong artist still can't auto-match at any
  setting. New validated settings keys: enrich_enabled (bool) +
  enrich_auto_threshold (0.5–1.01; >1.0 = "Always review", since a
  capped score can equal exactly 1.0). Read once per pass; disabling
  gates only the BACKGROUND matcher — manual search/fix stays available.
- Settings -> Library -> "Metadata matching" card: enable toggle,
  confidence select (85 / 90 / 95 / Always review), a Match Now button
  (new POST /api/enrichment/kick, single-flight like every other kick,
  demo-mode blocked), and a live status line fed by the same fetch as
  the review chip. Markup in index.html per the v3 settings pattern,
  wired by match-review.js, null-guarded so v2 no-ops.
- Review queue orders missing-data charts first — confirming those has
  the most to gain; complete charts only stand to be re-labelled.

Tests: threshold moves the auto/review boundary via settings; the
enable toggle gates matching but not the manual proxy; settings
validation; kick route; queue ordering; classify(auto_min=...) floors.
Full-suite failure set byte-identical to the pre-change baseline.
tailwind.min.css regenerated for the modal's utility classes.

* fix(library): lock MusicBrainz throttle across sleep + de-dup enrich queue (PR #710 review)

Hold a module-level lock across _enrich_throttle's read/sleep/write so the
background daemon and threadpooled sync search route serialize outbound MB
requests instead of bursting past the 1 req/s limit. De-dup the enrich queue
by filename so a changed-hash failed row isn't processed twice per pass.
