feat: SongCreator 씬 완성 — Beat Sage URL 지원, info.dat 메타데이터 자동 추출

- BeatSageUploader: audio_url 지원(UploadFromUrl), PollAndDownload 공통화, ZIP 500 오류 3회 재시도 - BeatSageConverter: info.dat 파싱(SongMetadata), BPM 자동 감지 → 노트 타이밍 변환에 적용 - SongCreatorManager: title/BPM 필수 입력 제거, 난이도 4개 자동 선택, GenerateFlowFromUrl 버그 수정 - NasPublisher: audioPath null 허용(URL 흐름에서 로컬 파일 없는 경우 스킵) - .gitignore/.gitattributes 초기 설정 Co-Authored-By: Claude Sonnet 4.6 <noreply@anthropic.com>
