Groom

Turn a rough idea into a scoped, labeled GitHub issue ready for the delivery pipeline. Use when the owner wants to capture a todo, feature, or bug as a real backlog item with scope, acceptance criteria, and a priority. Refines the idea over as many rounds as it takes — each round a fresh `product-manager` that has read the code, whose questions are asked one per message, each with a stated recommended default — and ends the loop only when every acceptance criterion is testable as written. Verifies bug reports read-only before scoping them, and offers a type:docs fast-track label for documentation-only work. First stage of the flow delivery workflow (see docs/workflow.md).
