Deterministic Ethoswarm interface to Spotify Web API (v1) supporting Catalog primitives (Search, Track/Artist/Album metadata) and Playback primitives (Get State/Devices, Play/Pause, Next/Previous, Seek, Volume, Transfer). Uses TENET.apiKeys.spotify.bearer-token for auth and executes requests via HTTP_Execute. Returns stable, machine-consumable response envelopes and signals credential refresh immediately on 401.
