수정: CLI timeout/cancel 후 session 오염과 Registry stop error 처리 개선

- CLI persistent 실행 중 ctx.Done() 발생 시 session을 정리하여 늦은 출력이
  다음 run에 섞이는 문제 해결
- CLI Execute에서 mutex lock/unlock 구조를 개선하여 race condition 방지
- Registry.Stop이 모든 lifecycle adapter의 Stop을 시도하고, errors.Join 대신
  first error 패턴으로 변경하여 한 adapter의 실패가 다른 adapter 정리를 막지 않도록 수정
- timeout 후 session 오염 방지 회귀 테스트 추가
- registry stop failure 후에도 preceding adapter stop이 호출되는 테스트 추가
- CLI partial profile rollback 테스트 강화
