Broque Thomas 529486a2d1 Foundation: typed Album/Track/Artist + per-provider converters ... New core/metadata/types.py with canonical dataclasses + classmethod converters for spotify/itunes/deezer/discogs/musicbrainz/hydrabase. Each converter is the single place that knows that provider's wire shape — addresses the duck-typing pattern Cin flagged. Pure additive: no consumer code changed. Follow-up PRs migrate consumers one at a time. Migration plan at docs/metadata-types-migration.md. Tests: 32 cases pin per-provider semantics + cross-provider invariants. Also stabilized a flaky discogs test that depended on local config state.		2026-05-03 22:21:32 -07:00
