Bring the ask-matt router up to date with the full skill set. It now maps five skills it was missing: tdd (woven into the main flow as the red-green engine implement drives), diagnosing-bugs (a new "Something's broken" on-ramp — there was previously no route for a bug), domain-modeling and codebase-design (a new "Vocabulary underneath" section), and grilling (the shared interview primitive). prototype is fleshed out as a standalone and the description broadens from "user-invoked skills" to "the skills". A maintenance rule is added to CLAUDE.md so any future skill add/rename/remove or flow change triggers an ask-matt re-check, beside the existing docs-page re-sync rule.
