Add 'favourite' rating tier for stronger recommendation signal
Favourite (star icon, amber) sits above liked and carries 2x weight in the recommendation engine. All positive-signal queries (GetLikedShows, GetBothLikedShows) now include favourites. Claude API prompts pass favourites separately for better taste profiling. Co-Authored-By: Claude Opus 4.6 (1M context) <noreply@anthropic.com>
