Release v1.1.0 - Configuration Simplification

Configuration Changes:
- Removed sync window logic from Spotify Import (no more SYNC_START_HOUR, SYNC_START_MINUTE, SYNC_WINDOW_HOURS)
- Simplified to: fetch on startup if cache missing, check every 5 minutes for stale cache
- Unified download folder structure: downloads/{permanent,cache,kept}/ instead of separate paths
- Removed Library:KeptPath config, now uses downloads/kept/

Documentation:
- Updated README with clearer Spotify Import configuration
- Updated .env.example to reflect simplified settings
- Removed MIGRATION.md from repository (local-only file)

Bug Fixes:
- Web UI now correctly displays kept tracks in Active Playlists tab
- Fixed path handling for favorited tracks
