feat: GAS_THIN_ADAPTER_POLICY_V1 Phase-1 Inventory 완료

tools/audit_gas_thin_adapter_v1.py 신규 작성:
- src/gas_adapter_parts/*.gs 9개 파일, 총 273개 함수 스캔
- allowed/forbidden/mixed/unknown 키워드 기반 분류
- Temp/gas_business_logic_audit_v1.json 출력 (gitignored)
- 이전 후보(forbidden) 23개 확인: sizing/stop_loss/take_profit/risk_score/decision

결과 요약:
- compliance_pct: 38.1% (allowed 104 / 273)
- forbidden: 23 (calcPrices_, calcTpQuantityLadder_, buildOrderBlueprint_ 등)
- mixed: 15 (collect + forbidden 겸용)

spec/39_gas_thin_adapter_policy.yaml 업데이트:
- migration_plan.status: PLANNED → IN_PROGRESS
- inventory_result 필드 추가 (수치 기록)
- inventory phase status: DONE
