⚡ Bolt: ncol 확인 시 불필요한 as.data.frame 제거

[seonghobae]

💡 What: aFIPC.R 내에서 컬럼의 개수를 구할 때 사용되는 ncol(as.data.frame(...))를 ncol(...)로 직접 변경했습니다.
🎯 Why: ncol()은 행렬(matrix)과 데이터프레임(data.frame) 모두에 적용이 가능한데도 불필요하게 as.data.frame으로 타입을 강제 변환하면, 행렬의 크기에 비례하는 메모리 할당(O(N) copy) 오버헤드가 발생하기 때문입니다.
📊 Impact: 불필요한 행렬 변환 시 발생하는 O(N)의 메모리 복사 비용을 완전히 제거합니다.
🔬 Measurement: 기존 기능의 동일성을 100% 보장하며, 테스트가 정상 통과(testthat::test_local())함을 확인했습니다.
