refactor(tokens): A-8 Batch 3 — PreviewPanel / DocumentViewer / +layout(toast)

가장 큰 위험 batch. Phase A 디자인 시스템 정착 마지막 mechanical refactor
(8 파일 8/8 누적 — core components 0 hit 달성).

PreviewPanel (53 hits → 0):
- bg-[var(--sidebar-bg)] → bg-sidebar (메인 aside)
- bg-[var(--bg)]         → bg-bg (input 배경)
- bg-[var(--surface)]    → bg-surface (hover)
- bg-[var(--accent)]     → bg-accent + hover:bg-accent-hover (저장 버튼)
- bg-[var(--error)]      → bg-error (삭제 확인)
- text/border 토큰 일괄 swap
- focus:border-accent (input)
- confidence 색상 (green/amber/red palette)은 plan B3 명시 없어 그대로

DocumentViewer (28 hits → 0):
- 뷰어 본체 bg-surface border-default
- 툴바 bg-sidebar
- 마크다운 편집 탭 bg-surface, edit textarea bg-bg
- 상태별 hover 토큰 swap
- 뉴스 article 태그 blue-900/30 그대로 (lint:tokens 미검출)

+layout.svelte (10 hits → 0):
- nav 잔여 var() (햄버거, 로고, 메뉴 링크) 토큰 swap
- 로딩 텍스트 text-dim
- toast 영역 의미 swap (plan B3 명시):
  * green-900/200  → bg-success/10 + text-success + border-success/30
  * red-900/200    → bg-error/10 + text-error + border-error/30
  * yellow-900/200 → bg-warning/10 + text-warning + border-warning/30
  * blue-900/200   → bg-accent/10 + text-accent + border-accent/30
- class:* 디렉티브 8개 → script TOAST_CLASS dict + dynamic class binding
  (svelte 5에서 슬래시 포함 클래스명을 class: 디렉티브로 못 씀)

검증:
- npm run lint:tokens : 360 → 269 (-91, B3 파일 0 hit)
- 누적 진행: 421 → 269 (-152 / 8 파일 완료, plan 정정 목표 정확 달성)
- npm run build       : ✅
- npx svelte-check    : ✅ 0 errors
- ⚠ 3-risk grep       : hover/border-border/var() 잔여 0건

A-8 종료 시점 상태:
- core components 8 파일: lint:tokens 0 hit ✅
- routes 7 파일 잔존 (~269): news 92, settings 47, documents/[id] 36,
  +page 28, documents 26, inbox 25, login 15
- lint:tokens 강제화 (pre-commit hook)는 Phase D + F 완료 후 별도 commit
