fix: launch-window changeset level + regenerate skill references (GraphQL removal follow-through)

- Changeset major → minor per the launch-window convention (the gate's
  own instruction; same treatment as #3486/#2377 — breaking rides minor
  without burning the whole fixed group's major).
- Drop the api/graphql.zod.ts entry from the skill-references mapping
  and regenerate (check:skill-refs gate).
