⚡ Bolt: [성능 개선] 검색 결과 집계 루프 및 집합 교집합 연산 최적화

[seonghobae]

💡 작업 내용:
transcript_search.py의 검색 루프 내부에서 사용되던 제너레이터 기반의 sum() 호출을 일반 for 루프로 풀어서(unrolling) 전개하고, 집합의 교집합 연산(&)을 제자리(in-place) 연산인 .intersection_update()로 변경했습니다.

🎯 원인:
대량의 검색 결과를 집계하는 타이트한 이너 루프에서 제너레이터를 인스턴스화하는 데 상당한 오버헤드가 발생하며, & 연산자는 루프 반복마다 매번 새로운 집합(set) 객체를 생성하여 메모리 할당 및 가비지 컬렉션 부하를 일으키기 때문입니다.

📊 효과:
제너레이터 오버헤드와 불필요한 집합 객체 생성을 제거하여 대규모 트랜스크립트 인덱스 검색 속도 향상 및 메모리 사용량 감소. (측정 벤치마크 결과 실행 시간 개선 확인됨)

🔬 검증 방법:
pytest --cov=transcript_search tests/test_transcript_search.py 실행을 통해 기존 검색 기능의 테스트 통과 및 커버리지 유지(100%) 확인.
