feat(scripts): all-in-one host-house.sh; free stale port; fail-fast join sync
- host-house.sh: one tmux session hosting a room (server window) plus your own
  GUI client window — builds, frees the port, waits for /health, then attaches.
- host-room.sh: free_port() kills any stale LISTENer squatting on the port so
  the bind can't fail with "address already in use".
- join.sh: cap each remote pull with `timeout` + GIT_TERMINAL_PROMPT=0 so an
  unreachable remote fails fast instead of hanging.
