- remove legacy _source/provider emission from the new metadata path
- update import, discovery, wishlist, and repair consumers to read source
- refresh the affected tests to match the new contract
- Let the wishlist service accept both track_data and spotify_track_data
- Preserve the backward-compatible wrapper while avoiding the keyword argument crash
- Add a regression test for the alias path
- add neutral wishlist payload helpers while keeping legacy Spotify aliases
- route wishlist removal and classification through generic track data
- keep API and service compatibility for existing callers
- add module-level loggers for the wishlist package instead of threading the web server logger through runtime objects
- default wishlist helper runtimes and cleanup helpers to their package logger while still allowing test overrides
- keep web_server.py as a thin caller that no longer injects its logger into wishlist flows
- add core/wishlist as the home for wishlist payload, resolution, state, processing, reporting, and selection helpers
- move wishlist-specific tests into tests/wishlist alongside the new package layout
- keep web_server.py and the import/search callers as thin adapters for now
