⚡ Bolt: O(N log N) 정렬 대신 O(N) 탐색 사용

[seonghobae]

💡 What: surveyFA.R에서 최솟값을 찾을 때 사용하던 names(sort(x))[1L] 패턴을 names(x)[which.min(x)]로 변경했습니다.
🎯 Why: sort(x)를 호출하면 전체 배열을 정렬해야 하므로 O(N log N)의 시간 복잡도가 발생합니다. 최솟값 하나만 필요한 경우에는 O(N) 선형 탐색을 수행하는 which.min()을 사용하는 것이 성능상 유리합니다.
📊 Impact: 요소 수가 많은 배열에서 반복적으로 최솟값을 찾을 때 불필요한 정렬 오버헤드를 제거하여 성능을 향상시킵니다.
🔬 Measurement: R/surveyFA.R 파일 내에 which.min(p_values)가 제대로 적용되었는지 확인하고 패키지 테스트 스위트를 실행하여 정상 동작함을 확인했습니다.

Closing as superseded by #178. Both replace the full sort() used only to select the minimum p-value with linear-time which.min(). #178 provides the same optimization behind a documented helper and adds focused surveyFA regression coverage for the selection/error path, whereas this PR couples the one-line change to broad Jules/markdown/build-ignore edits. #178 is therefore the narrower behaviorally evidenced review surface. No checks, reviews, or approvals transfer.
