- legacy duck-typed builder only checked the `album_type` key; deezer
uses `record_type`, tidal uses `type` (uppercase), some flattened
musicbrainz shapes use `primary-type` — all defaulted to album, so
EPs and singles ended up filed under Album/ in user templates that
reference $albumtype
- widen lookup to album_type / record_type / type / primary-type and
route through new pure `_normalize_album_type` helper that
case-folds + validates against the canonical token set
(album / single / ep / compilation), unknown → album
- typed-converter path (spotify / deezer / itunes / discogs / mb /
hydrabase / qobuz) unchanged — those were already correct
