🎨 Palette: 빈 디렉토리 상태 메시지에 접근성 개선 추가

[seonghobae]

💡 What: 빈 디렉토리 상태를 나타내는 <div> 요소에 role="status" ARIA 속성을 추가했습니다.
🎯 Why: 스크린 리더 사용자가 시각적으로 비어 있음을 나타내는 텍스트를 인지하기 어렵기 때문에 상태 메시지를 명확히 전달하기 위함입니다.
📸 Before/After: <div class="empty-dir">...</div> -> <div class="empty-dir" role="status">...</div>
♿ Accessibility: 정적 HTML에서도 상태 메시지에 role="status"를 부여하여 접근성을 향상시켰습니다.

Closing as superseded by #262 at exact head 642fc98ae09329e158e6cba9974a7894c89dd3e3. The same role="status" change is fully represented there, along with the aligned decorative folder icon, aria-hidden="true", and broader tests. Keeping one canonical branch avoids duplicate conflict repairs and redundant CI.
