Agent Skills: code-grill

Q↔R loop skill for the codesmith implementation workflow. Applies Kipling structure (What/How/Who/When/Why/Where) × grill-with-docs discipline × per-tag emphasis matrix to derive code-layer questions. Composes research dispatch instructions (in-memory, NOT a written artifact) per the 7 composable research patterns. Dispatches `researcher` across the hide-the-intent boundary — researcher receives questions + scope only, not the ticket. Synthesizes returns into the bundle's research file. Updates CONTEXT.md inline as terms surface. Scaffolds Decision Records when the three-condition gate fires. Loops until five readiness criteria are met (problem scoped, current state mapped, impact understood, edge cases identified, agent can articulate unprompted). Hands off to code-design when readiness is confirmed.
