wrapup: surface run start on both TUI and Desktop

The command blocks its turn and fires no message events, so nothing
indicated a running wrapup until completion. Send an ignored-message
start notice (TUI toast / Desktop persisted chat line) and a socket
action that kicks the sidebar's fast progress poll so the Wrapup row
appears immediately. Cargo.lock: sibling subc SDK version bumps.
