Native (CallKit+LiveKit) participants join the LiveKit room but not our WS mesh, so
peerIdForUid() had no mapping and sfuAttach dropped their track — the web caller stayed
on 'waiting' and never heard the native callee. Now sfuAttach/sfuDetach fall back to
keying the tile+audio by the LiveKit identity ('lk:'+id) when there's no mesh peer, and
stop the ringback. So a native<->web call crosses audio. Served — no rebuild.
