Broque Thomas e7ecaca3fd Fix MTV Unplugged & live-album false-quarantine pipeline
Closes #589. Tracks from MTV Unplugged / Live At / unplugged albums
consistently failed AcoustID verification with "Version mismatch:
expected (live) but file is (original)". Two upstream bugs fed into
the false positive — the AcoustID gate itself was correctly catching
the wrong file Tidal had selected. Codex diagnosed all three layers,
this fixes the two upstream causes and leaves the verifier alone.

Bug 1 — album-scoped library check false-misses owned albums

`core/downloads/master.py:184` scored "Shy Away (MTV Unplugged Live)"
(source title from playlist) vs "Shy Away" (local DB stored title)
with raw string similarity. Massive length asymmetry → ~0.3 → below
the 0.7 threshold → marked missing. Combined with the
`allow_duplicates and batch_is_album` short-circuit that disables
the global fallback for album downloads, the user's already-owned
album re-triggered every track for download. Explains the screenshot
showing "0 found / 7 missing" on an album the user manually placed.

New pure helper `core/matching/album_context_title.py:strip_redundant_album_suffix`
strips trailing parenthetical / bracket / dash suffixes whose tokens
are fully subsumed by the album context — at least one version
marker (live / unplugged / acoustic / session / concert / tour)
overlapping with the album, and every other token is either a
known marker, a year, a tolerated noise word, or a word from the
album title. Album-context-implied "live" added when the album
mentions unplugged / concert / tour / session.

Wired into the album-confirmed scope ONLY (not global matching).
Compares both raw and normalized source titles per album track and
takes the max similarity, so the helper returning the input
unchanged (when album doesn't imply version context) preserves
the pre-fix behavior.

Bug 2 — Tidal qualifier filter only ran on fallback searches

`core/tidal_download_client.py:345` set `is_fallback = attempt_idx > 0`
and only filtered when `is_fallback and required_qualifiers`. Primary
search returned all results unfiltered, so a query for "Shy Away
(MTV Unplugged Live)" could accept the studio cut if Tidal happened
to rank it first. Now the qualifier filter applies to BOTH primary
and fallback search attempts — log message updated to indicate
which path triggered.

Bug 3 — qualifier check ignored album.name

The legacy `_track_name_contains_qualifiers` only inspected the
track name. For concert / unplugged releases the live signal
typically lives in the album title, not the track title. New
`_track_matches_qualifiers` accepts a track object and inspects
both `track.name` AND `track.album.name`. Legacy helper preserved
to keep its existing test contract.

AcoustID version-mismatch gate at core/acoustid_verification.py
left intact — it correctly catches genuinely-wrong files that slip
through upstream filters. The In My Feelings (Instrumental) test
that pins this behavior continues to pass.

19 tests on the album-context helper covering MTV Unplugged
variants, dash/parens/brackets suffix shapes, year tolerance,
plural-form markers, the implied-live set, anti-regression cases
(instrumental/remix on a studio album must NOT be stripped),
empty/none defensive paths.

13 tests on the Tidal qualifier helper covering legacy
track-name-only behavior preserved, qualifier in track name alone,
qualifier in album name alone (the MTV Unplugged scenario),
multi-qualifier requirements, no-qualifiers always passes,
defensive against missing track.album, word-boundary avoiding
substring false-matches, _extract_qualifiers picking up live +
unplugged from the user's exact reporter query.

Full suite: 3053 passed.

"""Master worker for the missing-tracks download workflow.
`run_full_missing_tracks_process(batch_id, playlist_id, tracks_json, deps)` is
the single 580-line worker that orchestrates the entire pipeline:
1. PHASE 1 — Analysis: per-track DB ownership check, with album fast path
(lookup album by name+artist, match tracks within it) plus a
MusicBrainz release-cache preflight so per-track post-processing all
uses the same release MBID (prevents Navidrome album splits).
2. Wishlist removal for tracks already in the library.
3. Explicit-content filter.
4. PHASE 2 transition — if nothing missing, mark batch complete, update
per-source playlist phases, kick auto-wishlist completion handler.
5. Soulseek album pre-flight — search for a complete album folder before
falling back to track-by-track search, cache the source for reuse.
6. Wishlist album grouping — derive per-album disc counts and resolve
ONE artist context per album so collab albums don't fold-split.
7. Task creation with explicit album/artist context injection.
8. Hand off to download monitor + start_next_batch_of_downloads.
Lifted verbatim from web_server.py. Wide dependency surface (config, MB
caches, Soulseek client, source-page state dicts, multiple helper funcs)
all injected via `MasterDeps`.
