close #2183 Reusing a room means whoever enters first becomes the host, and moving the session to someone else's library meant everyone leaving and re-entering in the right order. The host can now promote any connected guest from the participant list (Watch Together screen and the in-player session sheet), with playback, control mode, and reconnect identities carried across. The relay owns the swap: a new `transferHost` message validates the sender is the live host and the target a connected modern-protocol guest, then swaps `HostPeerID` and the reconnect verifiers (each peer keeps its own token), persists the room, and broadcasts `hostChanged` to every peer. Clients flip roles in place: the controller swaps its role engine while keeping the session, message queue, and player attachment. A promoted guest seeds the coordinator with the room's last known intent (a paused room stays paused) and the known-peer roster so the fresh epoch re-gates instead of solo-starting; a demoted host falls back to a reconciler with a fresh clock sync and asks the new authority for state. Guests re-pin the host identity, reset their sequence, and re-converge their clocks. A rejected transfer (`not_host` / `peer_not_found`) surfaces as a toast instead of tearing the session down. Pre-transfer app builds in the room ignore `hostChanged` and stop following the room at the next transfer; targets on an old sync protocol are not offered the action.
