🛡️ Sentinel: [MEDIUM] 취약한 난수 생성 방식 수정

[seonghobae]

🚨 Severity: MEDIUM
💡 Vulnerability: 임시 파일 이름을 생성할 때 암호학적으로 안전하지 않은 Math.random()을 사용하고 있었습니다.
🎯 Impact: 임시 파일 이름이 예측 가능해져, 악의적인 사용자가 파일 충돌이나 예측 가능한 파일 이름을 악용한 로컬 보안 공격을 시도할 수 있습니다.
🔧 Fix: Math.random().toString(36).slice(2)를 암호학적으로 안전한 require('crypto').randomBytes(8).toString('hex')로 교체하였습니다.
✅ Verification: pnpm test를 통해 모든 기능이 정상적으로 동작하는지 확인하였습니다.
