🛡️ Sentinel: [CRITICAL] 대화형 프롬프트 입력 강제 변환(Coercion) 취약점 수정

[seonghobae]

🚨 Severity: CRITICAL
💡 Vulnerability: readline()의 입력을 검증할 때 ^[0-9]+$ 정규식을 사용하여, 매우 큰 숫자가 입력될 경우 as.integer()가 NA로 변환하고 결과적으로 하위 if 문에서 런타임 크래시가 발생할 수 있습니다.
🎯 Impact: 잘못된 입력으로 인해 자동화 환경 및 어플리케이션에서 프로세스가 강제 종료되는 취약점(DoS 위험)이 존재합니다.
🔧 Fix: 정규식을 ^[12]$로 수정하여 의도된 옵션(1 또는 2)만 정확히 통과하도록 엄격한 유효성 검증을 추가했습니다.
✅ Verification: Rscript -e "devtools::test()"를 통해 수정된 코드가 정상적으로 동작하는지 확인했습니다.
