New shared TrackContextMenu primitive with every option the Tauri
TrackMenu shows (flat — no submenus): Play now / Play next / Add to
queue / Create radio / Add to library / Add to mixtape / Add to
playlist / Share Qobuz link / Share Song.link / Make available offline
/ Go to album / Go to artist / Track info. Items already wired in the
MVP (play / play-next / queue / favorite) fire as before; the rest emit
their media-action and stay no-op until the backend lands. Used by
SearchTrackRow, AlbumPageView TrackRow, and ArtistPageView TrackRow.
