lock

Run:

PORT=$(cat ~/.cache/let-him-cook/port 2>/dev/null) && [ -n "$PORT" ] && curl -s "http://127.0.0.1:${PORT}/lock"

Report the response to the user. On success it returns locked:<basename> confirming which session is now the only one allowed to play audio. If the response is no session to lock — try submitting a prompt first, the bridge hasn't seen a UserPromptSubmit hook from this session yet — the user should try invoking the skill again (this very invocation should fix it for the next try).

If $PORT was empty, the bridge isn't running.
