refactor(kyberforge): address #154 review and drop commit steps from author skills

- instructions-author: keep two Gotchas, move the rest to the Step 2 contract
  and verify.md; add references/content.md on what belongs in an instructions
  file and tighten the template bullets to match
- instructions-author, skill-author, agent-author: remove the commit
  verification step; committing is out of scope for author skills
- skill-author 1.0.6, agent-author 1.0.4 (ADR-0022 patch bumps)
