feat: add agent/skill quality audit tooling + Grenier evaluation

AUDIT TOOLING (3 templates):
- Command: /audit-agents-skills (quick project audits)
  - 16-criteria framework (Identity 3x, Prompt 2x, Validation 1x, Design 2x)
  - Weighted scoring: 32 pts (agents/skills), 20 pts (commands)
  - Production grading (A-F, 80% threshold)
  - Fix mode with actionable suggestions
- Skill: audit-agents-skills (advanced audits)
  - 3 modes: Quick (top-5), Full (all 16), Comparative (vs templates)
  - JSON + Markdown output for CI/CD
- Scoring grids: criteria.yaml (externalized for reuse)

EVALUATION:
- Grenier agent/skill quality (3/5 - Moderate Value)
  - Gap: 29.5% deploy without evaluation (LangChang 2026)
  - Integration: Created audit command + skill + criteria
  - Industry context: 18% cite agent bugs as top challenge

DOCUMENTATION:
- Guide refs: 2 strategic call-outs (after Agent/Skill validation)
- CHANGELOG: New "Added" section + evaluation details
- README: Templates 106→107, Evaluations 49→24 (count corrections)
- reference.yaml: 10 new audit entries + updated counts

SYNC:
- Landing index.html: Templates 107, Evals 24, Quiz 257
- Landing examples/index.html: Templates 107

FILES: 14 changed, 4148 insertions (+1250 lines new audit content)
