create_event
Create a free group-scheduling event (like When2meet/Doodle) and get a shareable link. Use this when a human asks you to find a time for a group to meet. Returns a public event_url anyone can open (no login) to mark when they're free, plus an admin note. Then poll get_results to see the best time.
