#요약 (AI 작성)

ohah/zntc에서 주력으로 다중 포맷 빌드 기능 개발과 성능 프로파일링 인프라를 확장했습니다. Rollup 스타일의 zntc(input).write(output).close() API를 추가하고, OutputConfig + BundleOptions.output[]을 통해 여러 출력 포맷을 한 번에 지원하는 기능을 구현했습니다. 이어 모듈 페더레이션과 다중 포맷의 조합을 거부하도록 막는 로직과 CSS 공유 자산 정책을 문서화했습니다. 동시에 인크리멘트 빌드 성능 측정을 위한 프로파일링 시스템(M0-M8)을 구축하고, RequestedExports를 HashMap에서 플랫 배열로 변경하여 그래프 성능을 개선했습니다. ohah/ohah.github.io에서는 맞춤법 검사용 크론 작업과 개발 로그 관리를 진행했습니다.
