feat(commands): add /plugin-audit — 8-phase validation pipeline for skills and plugins
- Add commands/plugin-audit.md (distributable) + .claude/commands/plugin-audit.md (local invocation)
- 8 phases: discovery, structure validation, quality scoring, script testing,
security audit, marketplace compliance, ecosystem integration, domain code review
- Auto-fixes non-critical issues, only prompts user for breaking changes
- Integrates skill_validator.py, quality_scorer.py, script_tester.py, skill_security_auditor.py
- Domain-appropriate review via cs-* agents (engineering, product, marketing, etc.)
- Update product-team counts: 12→14 skills, 13→16 tools, 7→8 commands
- Add /code-to-prd and /plugin-audit to mkdocs.yml nav
- Regenerate docs (248 pages, 19 commands)
