Feature Description

Integrate Netease Cloud playlists with the app's playlist system, automatically syncing user playlists to application playlists.

Problem Statement

Previously, Netease Cloud playlist songs were imported into the unified music library, but the playlist organizational structure was not preserved. Users could not view or manage Netease Cloud playlists within the Playlists tab.

Solution

• Automatically create corresponding app Playlist objects when syncing Netease Cloud playlists
• Real-time content synchronization: song lists, playlist names, and metadata remain consistent
• Delete corresponding app playlists when Netease playlists are removed
• Clean up all associated app playlists when user logs out

Technical Details

• Injected UserPreferencesRepository into NeteaseRepository
• Added NETEASE_PLAYLIST_PREFIX constant to identify app playlists corresponding to Netease playlists
• Three new private methods:
  • updateAppPlaylistForNeteasePlaylist(): Creates or updates app playlists
  • deleteAppPlaylistForNeteasePlaylist(): Deletes app playlists
  • getAppPlaylistIdForNetease(): Generates app playlist IDs
• Modified sync logic in syncPlaylistSongs(), syncUserPlaylists(), and logout() to invoke these methods

User Experience Improvements

✅ All Netease Cloud playlists now appear in the Playlists tab
✅ Playlist names and song lists are automatically kept in sync
✅ Full support for existing playlist features (sorting, editing, etc.)
✅ Seamless UI integration without requiring additional user actions
