🎨 Palette: 시각적 호버 피드백 복원 및 숨겨진 텍스트 스타일링 개선

[seonghobae]

💡 What: 디렉토리/파일 링크에 커서를 올렸을 때(hover) 파일명에 밑줄이 생기는 피드백을 복원했습니다. :last-child CSS 선택자를 :nth-child(2)로 변경했습니다.
🎯 Why: 스크린 리더를 위한 숨겨진 텍스트(<span class="visually-hidden">)가 링크의 마지막 요소로 추가된 이후, :last-child 규칙이 숨겨진 텍스트에 적용되어 일반 사용자가 볼 수 있는 파일명에는 더 이상 밑줄 효과가 나타나지 않았기 때문입니다.
📸 Before/After: 링크에 커서를 올려도 밑줄 효과가 없던 것에서, 정상적으로 시각적 피드백을 제공하도록 수정되었습니다.
♿ Accessibility: 숨겨진 시맨틱 텍스트 구조를 손상시키지 않으면서 시각적 사용자 피드백을 성공적으로 복원했습니다.
