🎨 Palette: 빈 디렉토리 상태 메시지 접근성 개선 (role="status")

[seonghobae]

💡 What: src/main/kotlin/html4tree/main.kt의 빈 디렉토리 메시지(<div class="empty-dir">)에 role="status" 속성을 추가했습니다.
🎯 Why: 자동으로 생성된 디렉토리 트리가 비어 있을 때 스크린 리더 사용자가 현재 위치의 상태(빈 목록)를 포커스 이동 없이 명확히 안내받을 수 있도록 하기 위함입니다.
📸 Before/After: 시각적 변경 없음 (HTML 요소 속성만 추가)
♿ Accessibility: 상태 메시지 요소를 제공하여 시각 장애가 있는 사용자가 화면 내용을 파악하기 쉽게 접근성이 개선되었습니다.

Pull request overview

OpenCode cannot approve yet because required coverage evidence did not pass.

Review outcome

1. HIGH .github/workflows/opencode-review.yml:1 - Coverage evidence did not prove required test/docstring evidence

• Problem: The required coverage-evidence job result was failure, so OpenCode cannot establish approval sufficiency for this head.

• Root cause: Automated approval is only valid when the same-head coverage-evidence job proves supported repository test suites passed and configured docstring gates passed or were advisory, or reports not applicable because no supported source files or package manifests exist. Missing, failed, skipped, unavailable, or unsupported-tooling test evidence is a blocker.

• Fix: Install or configure the repository test/docstring evidence tooling when source files or package manifests exist, rerun the current-head coverage-evidence job, and approve only after it reports success with required evidence or explicit no-source not-applicable evidence.

• Regression test: Keep the approval branch checking needs.coverage-evidence.result == success before posting APPROVE, and publish REQUEST_CHANGES when coverage-evidence blocker states such as cancelled, skipped, failed, unsupported-tooling, or below-100 evidence are present.

• Result: REQUEST_CHANGES

• Reason: coverage-evidence result was failure, so required test/docstring evidence was not proven for current head 5381d5ca580ac3e2be58c05116acb8e33f3fd200.

• Head SHA: 5381d5ca580ac3e2be58c05116acb8e33f3fd200

Closing as superseded by the protected branch: role="status" is already present and tested on the generated empty state. Draft #360 is the single post-#363 path for remaining evidence-based accessibility/readability work. No check or review from this duplicate head is reused.

Understood. Acknowledging that this work is now obsolete and stopping work on this task.
