기존 AriMail 인스턴스 ↔ HAL 관리형 MailService/Node 가져오기: hal/mailsvc.mjs(등록부·dry-run·트랜잭션 적용·되돌리기·heartbeat 동기화) + scripts/mail-discover.mjs(읽기 전용 discovery) + CLI/운영자 API/화면, 테스트 9건, RUNBOOK §9

- mail_services(도메인 단위 논리 리소스, 불변 id, 출처 권한, 도메인별 active owner 1 — 부분 유일 인덱스)·mail_imports 표 추가(기존 표 변경 없음)
- discovery 문서에 비밀값이 있으면 거부(참조만 저장), 충돌·중복·누락은 전체 거부, 적용은 트랜잭션 + 감사(immutable), 재적용 멱등, 적용 단위 되돌리기
- hal/index.mjs: mail-import · mail-import-rollback · mail-services · server-token(시스템 신원 토큰, 감사) / app.mjs: /ops/api/mail-services* / ui: /ops/mail HAL 관리형 표 + 포털 중계(#portal-mail)
- core.heartbeat → syncFromHeartbeat(Agent 의 arimail 모듈 상태를 last_sync·health 로 반영, 행 없으면 무관)
