[CLAUDE] Docs: setup RAG Framework v1.3 governance + eval framework

- docs/governance/README.md: Path B delegation stub → AI_INFRA canonical
  Phase/BC vocabulary documented (9 phase + 10 BC SOLUTION_ERP-specific)
- .claude/rag.json: add _decision_log block (10 rationale entries) +
  add .claude/agents/**/*.md to corpus_paths (fix Case D harvest gap)
- eval/evaluator.md: inline executor spec v1.0 (Spec A strict)
- eval/golden-set-solution_erp.jsonl: 14-entry golden set v1.1
  (5 gotcha + 3 pattern + 3 decision + 3 negative)
- eval/runs/2026-05-26-baseline-v1.0-failed.json: v1.0 attempt
  recall@5=0.455 FAIL — root cause diagnosis Case A/C/D
- eval/runs/2026-05-26-baseline-v1.1-pending.json: v1.1 attempt
  pending CLI restart for accurate numbers
- eval/trial-state-lock.json: 2-section split (quality_gate +
  drift_monitor) per v1.3 §6.2, 4-week milestones 2026-05-26 → 2026-06-23

CRITICAL lesson: bootstrap.py --project flag overrides collection name only.
Use --config D:\...\SOLUTION_ERP\.claude\rag.json for correct project root.
Old projects.json had root_path=AI_INFRA for solution_erp (Anti #24) — FIXED.
