`colnames(newformXDataK[colnames(newFormModel@Data$data)])` 와 같이 이미 알고 있는 열 이름으로 데이터프레임을 서브셋팅하여 다시 열 이름을 구하는 로직을 제거했습니다. R에서 데이터프레임을 서브셋팅하는 것은 O(N) 메모리 할당 및 복사 오버헤드를 발생시킵니다. 이를 `colnames(newFormModel@Data$data)`를 직접 사용하도록 수정하여 실행 속도를 향상시키고 불필요한 메모리 사용을 방지했습니다. 해당 최적화에 대한 내용은 `.jules/bolt.md` 저널에 기록되었습니다.

💡 What: 불필요한 데이터프레임 서브셋팅 구문을 최적화 (
colnames(df[cols])->cols)🎯 Why: R에서 데이터프레임을 부분집합(subset)으로 추출할 때 발생하는 O(N) 복사/할당 오버헤드를 방지하여 성능을 향상시키기 위함입니다.
📊 Impact: 열 추출과 관련된 루프 내 성능 개선 및 O(N) 메모리 할당 감소를 달성했습니다.
