feat: DATA_GATED 진척도 추적 + 팩터 shadow 자격 평가 + routing_gate 실측 보정

- tools/build_data_gated_progress_v1.py: WBS-2.5/4.1~4.3/RELEASE_GATE_TRUTH 실측 진척도
  (sector_flow 21/30일, T+20 0/30건, honest_proof 45.1/70.0)
- tools/build_factor_shadow_eligibility_v1.py: 149개 팩터 shadow 자격 평가
  (eligible=24, partial=37, blocked=38)
- spec/41: DAG step_count 63→67, 신규 4노드 추가
  (build_data_gated_progress, build_factor_shadow_eligibility,
   build_strategy_routing_audit, build_horizon_rebalance_plan)
- spec/30: routing_gate 실측 보정 — SHORT 71.4%는 오류,
  실제 원인은 MID 75.0% > 50% 상한 (2026-06-14 실측)
- spec/13: DATA_GATED_PROGRESS_V1, FACTOR_SHADOW_ELIGIBILITY_V1,
  STRATEGY_ROUTING_AUDIT_V1 formula 등록
