🎨 Palette: 루트 디렉토리 이름 Fallback 추가

[seonghobae]

💡 What (추가된 기능)

• 파일 시스템 루트 디렉토리 처리 시 File.getName()이 빈 문자열을 반환하는 경우, absolutePath를 Fallback으로 사용하여 <title> 및 <h1>를 생성하도록 변경했습니다.

🎯 Why (해결한 사용자 문제)

• 기존에는 루트 디렉토리에서 생성된 HTML 트리의 <title> 및 <h1> 요소가 완전히 비어 있어, 사용자(특히 스크린 리더 사용자)가 현재 위치를 파악하기 어려웠습니다.

📸 Before/After

• Before: <title></title>, <h1></h1> (루트 디렉토리의 경우)
• After: <title>/</title>, <h1>/</h1> 등 absolutePath를 표시.

♿ Accessibility (접근성 개선 사항)

• 스크린 리더가 루트 디렉토리에서도 명확하고 의미 있는 페이지 제목과 헤딩을 소리내어 읽을 수 있게 되어 내비게이션 접근성이 향상되었습니다.

Pull request overview

This PR improves the generated directory listing HTML so that when File.getName() is empty (notably for filesystem root directories), the page <title> and <h1> fall back to using the directory’s absolutePath, improving context for users (including screen reader users).

Changes:

• Add dirNameToDisplay fallback (name → absolutePath when empty) and use it for <title>/<h1> in process_dir.
• Add a unit test covering the empty-name fallback behavior.
• Document the learned rule and action in .jules/palette.md.

Closing as superseded by draft canonical #364. The same absolute-path fallback for filesystem roots is retained there under a bounded post-#363 accessibility contract. #364 must still centralize one escaped display label, prove root and ordinary generated pages, add APA 7 doctoring and changelog, and pass fresh exact-head quality/security checks plus independent approval. No evidence from this duplicate head is reused.
