New crate for Last.fm, ListenBrainz, and MusicBrainz integrations.
Designed to work WITHOUT Tauri for TUI/headless clients.
Modules:
- lastfm: Scrobbling and now-playing via Cloudflare Workers proxy
- listenbrainz: Direct API client with user token auth
- musicbrainz: Entity resolution with rate limiting
Features:
- `cache` (default): SQLite persistence for offline support
- ListenBrainz: Credential storage, offline listen queue
- MusicBrainz: Resolved entity cache with TTL
Architecture:
- Pure async Rust, no Tauri dependencies
- Shared error types via IntegrationError enum
- Rate limiting for MusicBrainz (1 req/sec direct, faster via proxy)
