library: one record, one recents row, however it was played
A saved album that also streams showed up twice in the sidebar's recently-played — once as the library album, once as the catalog album — because a play row carries album_id only when the played FILE was a library track, so streamed plays of the same record grouped separately under their catalog id. The plays table already holds the bridge: any play that carried BOTH ids (a local track played with the catalog page on screen) pins that catalog album to that library album, by exact ids, never by name. recent_albums now folds linked catalog plays into the library row — which also keeps the row's timestamp honest when the newest listen was the streamed one — and drops them from the catalog arm. Deleting the album from the library dissolves the link, and its catalog plays stand alone again. Regression test reproduces the exact two-Origins shape: dual-id play plus a newer streamed play must come back as one library row wearing the streamed play's timestamp, sorted above an older unrelated record.
