🎨 Palette: [UX improvement] 다국어(RTL) 텍스트 지원 추가

[seonghobae]

💡 What: HTML로 렌더링되는 텍스트 요소(<h1 dir="auto"> 및 <span dir="auto">)에 dir="auto" 속성을 추가하여 다국어(RTL) 텍스트 지원을 개선했습니다.
🎯 Why: 파일 서버는 다국어 파일 및 폴더명을 지원해야 하며, 오른쪽에서 왼쪽으로 쓰는 문자(Right-To-Left)가 포함된 이름이 일반적인 LTR 레이아웃에 표시될 때 텍스트 방향이 잘못 설정되어 깨지는 것을 방지해야 합니다.
📸 Before/After: 기존에는 RTL 문자열을 렌더링할 때 텍스트 정렬이 잘못되었으나, dir="auto" 적용으로 각 텍스트 요소가 콘텐츠에 맞게 자동 정렬됩니다.
♿ Accessibility: 다국어 지원이 향상되어 스크린 리더와 브라우저의 양방향 텍스트(BiDi) 호환성을 확보했습니다.

@jules Please repair this existing branch in place; do not create a new PR.

Fresh review of exact head 5b103644d1168166d8bd474e46177107bfa0638d finds a valid BiDi intent but an over-broad implementation/evidence scope. Keep dir="auto" only on user-controlled text whose base direction is genuinely content-dependent: the rendered directoryName heading and rendered fileName text. Remove it from the literal .. parent marker and the fixed Korean empty-state message; those strings have known direction and do not need content-derived directionality. Reconcile the empty-state markup with canonical Draft #590 instead of preserving/reintroducing its role="status" contract.

Also narrow .jules/palette.md/PR claims: do not claim that layout was demonstrably broken before or that screen-reader/BiDi compatibility is fully 'secured' without browser evidence. State only the semantic reason and verified markup contract. Add focused regressions with mixed RTL/LTR user-controlled directory/file names that prove escaped text is wrapped in the intended dir="auto" nodes, while fixed UI copy/parent marker remain unchanged. Do not add RTL direction to hidden fixed Korean labels.

Delivery acceptance: normal descendant only; preserve any intervening valid delta; exact generated markup and existing escaping/navigation tests GREEN; add browser/responsive evidence before claiming UI resilience; keep Draft until exact-head CI/security/review gates are terminal. No force-push, destructive rebase, no-op retrigger, self-approval, or gate weakening.

I have narrowed the scope of dir="auto" to only the user-controlled text (<h1> directory name and <span> file names). The fixed parent marker .. and the empty directory message now retain their known direction. I have also reconciled the empty-state markup by removing role="status". The claims in .jules/palette.md have been narrowed, and I have added a specific regression test confirming the correct behavior with mixed RTL/LTR content.
