feat: integrate /design-html into design skill pipeline

- design-shotgun: Step 6 option B now chains to /design-html
- design-consultation: suggests /design-html after shipping DESIGN.md
  (conditional on screen-level output, not tokens-only)
- plan-design-review: expanded chaining to include /design-shotgun
  and /design-html alongside review skills
