⚡ Bolt: [성능 개선] Promise.all을 활용한 비동기 병렬 파일 읽기 최적화

[seonghobae]

💡 What:

• readFileSync를 사용하는 동기적인 파일 읽기 루프를 Promise.all과 fs.promises.readFile을 사용한 비동기 병렬 처리로 리팩토링했습니다.
• src/cli.ts의 runCommand 래퍼가 비동기 함수를 지원하도록 업데이트했습니다 (fn: () => T | Promise<T>, Awaited<T>).

🎯 Why:

• 로컬 CLI 환경에서 다수의 파일을 조회(listUseCases, listActors 등)할 때 동기적 I/O(readFileSync)가 이벤트 루프를 블로킹하여 전체적인 성능 저하를 유발하는 병목 지점을 발견했습니다. 비동기 I/O로 전환하여 다수의 파일을 동시에 읽어들이도록 개선했습니다.

📊 Impact:

• CLI 환경에서 대량의 파일(수십~수백 개 이상)을 읽어들일 때 이벤트 루프 블로킹을 방지하고 I/O 병렬성을 극대화하여 조회(list*) 커맨드의 응답 속도와 전체 성능이 향상됩니다.

🔬 Measurement:

• pnpm test 명령어를 실행하여 기존 기능들이 비동기 환경에서도 완벽히 동작하는지 확인합니다. (모든 84개 테스트 통과 완료)
