🎨 Palette: 빈 디렉토리 이름 폴백 추가 (접근성 개선)

[seonghobae]

💡 What: 이름이 빈 디렉토리(예: 최상위 루트 등)일 때 절대 경로를 보여주도록 폴백(fallback) 메커니즘을 추가했습니다.
🎯 Why: 디렉토리 이름이 비어 있을 경우 <title> 및 <h1> 태그가 비어 있어, 화면 판독기(스크린 리더) 사용자가 현재 위치를 전혀 파악할 수 없는 심각한 접근성 문제를 해결하기 위함입니다.
📸 Before/After: 루트 디렉토리 크롤링 시 <title></title> -> <title>/absolute/path</title>
♿ Accessibility: 비어 있는 시맨틱 태그(title, h1)를 방지하여 화면 판독기의 탐색 및 컨텍스트 이해도를 크게 향상시켰습니다.

Pull request overview

Note

Copilot couldn't run its full agentic review because it didn't start before the timeout. Make sure your repository has a runner available, or add a copilot-code-review.yml file specifying one with the runs-on attribute. See the docs for more details.

Adds a fallback display name for directories that have an empty name (e.g., filesystem root) so generated HTML never contains empty <title> / <h1>, improving screen-reader accessibility.

Changes:

• Add dirName fallback to absolutePath when curr_dir.name is empty, and use it in <title>/<h1>.
• Add a unit test validating HTML output for an “empty name” directory case.
• Document the accessibility learning/action in .jules/palette.md.
