Add a BRANCH guard (default: main) so launching the house never demos a
stale checkout. ensure_branch() switches to $BRANCH before the cargo build,
refuses when the tree is dirty (won't clobber uncommitted work), and no-ops
when already on-branch or when BRANCH= is passed to keep the current checkout.

- 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.
