docs(release): REL-003 통합 confirmed — BAT-010~013 (safety-sell + kill-switch + multi-instance)

REL-003/004/005를 단일 app-service 릴리즈로 통합(사용자 결정). REL-003에
BAT-010·011(dcy-007 safety-sell) + BAT-012(dcy-008 kill-switch) +
BAT-013(dcy-009 multi-instance)를 묶고 rename, REL-004/005 draft 폐기.

- 파일 rename: rel-003 core-autonomous-safety-sell → safety-killswitch-multi-instance
- Scope/Rollout/Rollback/Verification 통합 (⚠️ --config 필수화 파괴적 기동 변경 +
  제어 큐 pause.req→control.req + 마이그레이션 004/005 + LIVE safety-sell/kill_switch 안전 주의)
- confirm-release: draft → confirmed (단위 271 + 인프라 게이트 301 passed + 전 e2e PASS)
- releases/index: REL-003 통합 행, REL-004/005 제거
