"""`/goal <text>` kicks the loop with a short pointer when the user's last message already carries the goal.

In one run `/goal <2,000-char handoff note>` was issued 16 minutes after the same note had been pasted as
a user message; the kickoff re-sent it and the agent spent 11 API calls / 6 min deciding it was a replay.
