sbxh6Downloader v0.1.0: iframe → sessionStorage queue + page navigation

- iframe/팝업/XHR 대신 페이지 직접 이동 방식으로 전환
- sessionStorage 기반 큐로 전체 에피소드 연속 다운로드
- 동적 scrollHeight에 대응하는 lazy 로딩 트리거
- 공통 헬퍼: downloadImagesAsZip, getImagesWithLazyLoad
- GM_unregisterMenuCommand로 메뉴 중복 등록/배지 누적 해결
- 안전한 로거(log)로 console 차단 사이트 대응
- Next.js SPA pushState/replaceState 감지하여 메뉴 재등록
