For a replica (federated) space, members on the home server and other peers join/leave over time. The home server fans these out so replicas stay current; the client must apply them to the member list live.

What to do

• Handle member join/leave gateway events for federated spaces, inserting/removing remote (qualified) members in the member list controller.
• Reconcile the membership snapshot received at join time with subsequent fanout events (no duplicates, no stale members).

Acceptance

• Joining a federated space shows the current member set; later remote joins/leaves update the list without a reconnect.

Server reference

• Member join/leave fanout: commit f7366f8 (member join/leave fanout); payloads in src/federation/outbound.rs (member_join_payload/member_leave_payload).
