Browse songs now carry their context in the mediaId (songctx:<contextId>|<songId>). A new onSetMediaItems override expands a single tapped song into its full list (Favoriten / album / playlist) and returns it with the tapped index as the start position, so playback continues through the rest instead of stopping after one song. onAddMediaItems shares the same resolver; onGetItem resolves context songs too.
