🛡️ Sentinel: [MEDIUM] readline 입력 시 정수 오버플로우 방지 유효성 검사 수정

[seonghobae]

🚨 Severity: MEDIUM
💡 Vulnerability: 대화형 readline() 숫자 입력 시 상한 없는 숫자 클래스(예: ^[0-9]+$)에 대해 정규식 확인을 통과한 지나치게 큰 숫자 문자열이 as.integer()에서 NA로 평가되어 후속 프로세스 충돌을 유발하는 정수 오버플로우 강제 변환 취약점.
🎯 Impact: 검증되지 않은 대규모 숫자가 입력될 경우 프로세스가 충돌하거나 예상치 못한 동작이 발생할 수 있습니다.
🔧 Fix: ^[0-9]+$와 같은 상한 없는 숫자 클래스 대신 ^[12]$처럼 정확히 기대하는 값과 엄격하게 일치하는지 확인하도록 수정했습니다.
✅ Verification: grep -n 'grepl("\^[12]\$", n)' R/aFIPC.R를 통해 정규식이 변경된 것을 확인했으며, Rscript -e "testthat::test_dir('tests/testthat')"를 통해 모든 테스트가 정상적으로 통과함을 확인했습니다.

📝 Info: Prompt input handling behavior change

Tightening the accepted input from any digits to only 1/2 changes prompt handling: inputs like 3 or 01 now re-prompt up to three times instead of falling through to the downstream domain error. Consistent across all three prompts; no new test fixtures accompany the change.
