Groove Utilities Task Create

This is the canonical task creation interface for the Groove workflow system. It writes tasks to your configured backend (beans, Linear, or GitHub) with proper structure: title, type, status, optional parent, and a rich body for any non-trivial work. The body format is prescribed with Context, Goal, Acceptance Criteria, and Links sections. Default status is in-progress, not todo, because tasks get created when you're already doing the work. Other Groove skills are meant to call this one rather than rolling their own creation logic. If you're building on top of Groove's task system, this is your entry point.
