작업

1. MITC4-KERNEL-007과 MITC4-PHYSREC-001을 먼저 작성한다.
2. Mitc4Shell 내부에 global element displacement 24개를 받아 physical-only shell recovery를 반환하는 candidate seam을 최소 구현한다.
3. Fixed GP1..GP4에서 local frame, eight generalized strain/resultant를 계산하고 BOTTOM/MIDDLE/TOP에서 direct [S11,S22,S12]를 계산한다.
4. Physical element strain energy만 반환하며 drilling stiffness/action은 모든 physical recovery와 energy에서 제외한다.
5. Pure drill vector가 stabilized action은 가지지만 모든 physical recovery/energy가 zero임을 검증한다.
