Agent Skills: nuqs-scaffolder

Scaffolds URL-state filters for a Next.js page — typed `searchParams.ts` parser map and a `<Filters />` client component backed by `useQueryStates`. From a single JSON spec, generates four files in lockstep — client parser map, server loader/cache/serializer, client component, and Vitest test — all sharing the same parser definitions per the nuqs Standard Schema pattern. Trigger even when the user only says "add filters to /search" or "I need a typed query string for this page" — both are exactly this skill's job.
