feat: Layer 프리미티브 (Drawer / Modal / ConfirmDialog / Tabs)

UX/UI 개편 Phase A-7. uiState와 결합한 layer/dialog 컴포넌트.

신규 컴포넌트 (lib/components/ui/)
- Drawer.svelte: 단일 slot drawer (id: 'sidebar' | 'meta').
  ui.isDrawerOpen(id)로 표시 여부 결정. 새 drawer 열면 이전 drawer 자동 close.
  side(left/right) + width(sidebar/rail). backdrop 클릭으로 close.
  z-drawer 사용. 8대 원칙 #2.

- Modal.svelte: stack 지원 modal (5대 원칙 #2 — confirm 위에 nested 가능).
  native <dialog> 대신 div 기반 — top-layer가 단일이라 <dialog>로는 stack 불가.
  z-index = z-modal + (stackIndex * 2): backdrop과 panel을 별개의 stacking
  context로 두기 위해 *2. 최상단 modal만 focus trap + 키보드 nav 활성,
  아래는 inert 처리. 수동 Tab/Shift+Tab cycling.
  closable + IconButton(X) 헤더, footer snippet 지원.

- ConfirmDialog.svelte: Modal 위 얇은 wrapper. 삭제/되돌릴 수 없는 작업에
  사용. tone(danger/primary), confirmLabel/cancelLabel, onconfirm 콜백.
  ui.openModal(id)로 호출.

- Tabs.svelte: ARIA tablist + tab + tabpanel.
  좌우 화살표 / Home / End 키 nav, \$props.id() 기반 SSR-safe ID.
  tabs: { id, label, disabled? }[], value \$bindable.
  children snippet은 (activeId) => UI 시그니처 — DocumentViewer 편집/미리보기
  토글 등 단일 컨테이너 레이아웃에 쓰기 좋게 설계.

이로써 Phase A 프리미티브 13종 완비:
  Button, IconButton, Card, Badge, Skeleton, EmptyState,
  TextInput, Textarea, Select,
  Drawer, Modal, ConfirmDialog, Tabs.

모든 컴포넌트는 Svelte 5 runes mode strict, @theme 토큰만 사용,
focus-visible ring 통일, slot은 {@render children?.()}로 작성.

svelte-check: 0 errors / 8 warnings (전부 기존 latent, 새 코드 무관)
build: 2.07s 무경고

남은 Phase A:
- A-8 토큰 swap (Sidebar/TagPill/UploadDropzone/PreviewPanel/DocumentCard/
  DocumentTable/+layout toast — baseline 421건 → 0건)
- A-9 __styleguide 라우트 (전체 시각 검증 + Modal stack 데모)
