executor: disc=1 now generates '1-01' prefix (same as disc=2 → '2-01'),
so multi-disc albums have consistent D-TT scheme throughout.
Single-disc tracks without disc tag stay as plain 'TT'.
hint_extractor: tracklist pattern 2 now requires '.' ')' or ':' as separator
(not bare whitespace) — prevents false-positive matches like
'2 x CD, Compilation, Remastered' being parsed as track 2.

hint_extractor:
- _norm_for_match(): strips all non-alnum for punctuation-agnostic comparison
- _catalog_key(): extracts BWV/Op./K./HWV/... catalog number for matching
(fixes abbreviated filenames like "Fantasia_Cm_BWV_562" vs "Fantasia In C Minor, BWV 562")
- Matching priority: exact number+disc → exact title → fuzzy title → catalog number
- Tracklist disc+track OVERRIDE M3U position when a match is found
(M3U is only used as last fallback; fixes wrong alphabetical ordering)
metadata_resolver:
- LLM prompt now defines artist/albumartist roles explicitly
(artist = composer for classical; albumartist = performer/interpreter)
- LLM albumartist can override dir_artist when confidence < 0.4
- _build_track_proposals: when track artist == albumartist (performer from filename),
composer (album-level artist) is used as track artist instead
- Tracklist header (first lines before tracks) included in LLM prompt
for label/year/album-title discovery
- import re added (was missing)

scanner: nicht in Unterordner wenn Root Audio-Dateien enthält (verhindert
Doppel-Scan bei versehentlichen Unterordner-Kopien); nur Disc-Ordner
(CD1, Disc 2…) werden bei Multi-CD-Alben rekursiert.
hint_extractor: M3U/Playlist-Dateien als Track-Reihenfolge-Quelle; BOM-
Bereinigung; Tracklist-Matching auch per Titel (nicht nur per Nummer);
tracknumber=0 wird als 'keine Nummer' gewertet.
metadata_resolver: sequenzielle Fallback-Nummerierung (1,2,3…) für Tracks
ohne Tracknummer — verhindert '00'-Präfix beim --rename; dir_artist hat
Vorrang vor 'Various Artists'-Heuristik; LLM darf bei Konfidenz <0.3
auch bestehende Werte korrigieren (Tippfehler im Verzeichnisnamen).

AI-powered per-album pipeline: scan → local hints → MusicBrainz/Discogs/Claude
resolve → cover art → interactive or auto review → tag write + rename + report.
All external dependencies optional; 17/17 unit tests passing.
