Each participant card gets a star affordance: a clickable outline star (☆) that
adds that peer to your friends list, or a non-interactive gold filled star (★)
once they're already a friend (hidden while the friends store is read-only). The
add pulls the peer's live presence name + address from the room roster and passes
addr: Some(..) to CoreCommand::AddFriend, so the new friend is reachable
immediately — no waiting for a future call to seed last_addr the way a bare
add-by-id does. Name sanitized, short-id fallback; idempotent in core; no-op if
already a friend. New AppMessage::AddFriendFromRoom(EndpointId).
clippy --all-targets clean, 257 lib tests green. UI wiring screenshot-pending: the
star + click need a live 2-machine call (a peer in the room) to verify visually.
