Update docs, skill counts, and UX/setup-engine skills for v0.4.0

- Update skill count to 66 and hook count to 12 across README, skills-reference, and badges
- Add QA & Testing section to README and skills-reference (qa-plan, smoke-check, soak-test, etc.)
- Add Input & Platform section to technical-preferences.md (populated by /setup-engine)
- Document post-compact, notify, and validate-skill-change hooks in hooks-reference
- Expand /setup-engine, /ux-design, /ux-review, /design-system skills with input/platform context
- Restructure workflow-catalog: move UX steps into pre-production phase, improve descriptions
- Expand UPGRADING.md and WORKFLOW-GUIDE.md with v0.4.0 guidance
- Add skill-flow-diagrams examples and CODEOWNERS
