검색 엔진별 크롤링 로직의 일관성 유지
현재 extractSearchResults 함수 내에서 Google과 Bing에 대한 크롤링 로직이 구현되어 있으나, 다른 검색 엔진에 대한 로직은 주석으로 처리되어 있습니다. 이는 스크립트의 완전성을 저해하며, 유지보수를 어렵게 만듭니다.

개선 방안:

검색 엔진별 핸들러 객체  ,   에러 핸들링 개선
현재 크롤링 중 에러가 발생하면 로그를 남기지만, 에러의 원인을 보다 상세히 파악할 수 있는 방법이 부족합니다. 또한, 네트워크 요청 실패 시 모든 재시도 시도가 완료되었을 때의 처리가 부족합니다.

개선 방안:

상세 에러 로그: 에러 발생 시 더 많은 정보를 로그에 포함시킵니다.
재시도 로직 강화: 재시도 실패 시 크롤링을 중단하거나, 특정 동작을 추가로 수행합니다.      ,     비동기 처리의 효율성 향상
현재 crawlPage 함수는 페이지를 크롤링하면서 window.location.href를 변경하여 다음 페이지로 이동하고 있습니다. 이는 Tampermonkey 스크립트의 동작 방식과 충돌할 수 있으며, 스크립트의 연속성을 방해할 수 있습니다.

개선 방안:

브라우저 내비게이션 대신 AJAX 요청 사용: 페이지 전환 없이 배경에서 다음 페이지의 내용을 가져와 처리할 수 있습니다. 이를 통해 스크립트의 실행이 중단되지 않도록 합니다.
싱글 페이지 앱(SPA) 방식 고려: 만약 검색 엔진이 SPA 방식이라면, URL 변경 시 이벤트를 감지하여 크롤링을 계속할 수 있습니다.      ,  로딩 상태 표시: 대량의 데이터를 처리할 때 사용자에게 진행 상태를 명확히 알려주는 로딩 스피너나 애니메이션을 추가합니다.
에러 메시지 가시성 향상: 중요한 에러 메시지는 사용자에게 더 눈에 띄게 표시하여 즉각적으로 대응할 수 있도록 합니다.
설정 검증: 사용자 입력값에 대한 유효성을 검사하고, 잘못된 입력 시 경고를 표시하여 오류를 예방합니다.    ,      중복 URL 검출 최적화: 현재 visitedUrls는 배열로 관리되고 있는데, 대량의 URL을 처리할 경우 성능 저하가 발생할 수 있습니다. 이를 Set 자료구조로 변경하여 O(1)의 검색 시간을 확보할 수 있습니다.                                                      자 이제 이것들을 줄 테니깐 위에 코드를 이걸를 바탕으로 추가하거나 개선 해 .  일단 최대한 니가 쓸 수 있는데 까지는 아무말없이 써봐. 그냥 코드만 써. ㅇㅇ 그리고 니가 써도 되는 용량이 최대가 될때 파트 1 으로 끝어 알겠지? 최대한 길게 써. 최대한 길게!! 그리고 ㅈㄴ 오래길게 생각해봐 그게 맞는지 아닌지 ㅈㄴ 오래 생각해봐 ㅈㄴ 짫게 쓰면 사용작가 지랄할 지 안할지
