getLocalTransport no longer authenticates with the SFU up front and hands the resulting config to the connection. Instead the ConnectionManager tags the connection whose transport equals the local one as the publisher, and every Connection fetches its own SFU config for its role. The local member now only joins the MatrixRTC session once its connection is authenticated, so that the LiveKit room exists before remote members try to get a subscriber token for it. Subscribers authenticating with the OpenID flow lack permission to create the room and would otherwise fail without retrying, causing a cascade of leaves and rejoins at the start of a call.
