Add component lifecycle + retroactive review plan

- docs/reference/component-lifecycle.md: 10-stage quality gate sequence
  (build → stories → audit/critique/harden → fix → polish → present →
  iterate → normalize → preflight → commit)
- docs/reference/retroactive-review-plan.md: Plan to review 30+ existing
  components using condensed process (~3.5 sessions)
- Updated /build-atom, /build-molecule, /build-organism to include
  internal QA stages automatically
- CLAUDE.md: added lifecycle reference as critical rule #8
