9798cda41e Add Axios interceptor for automatic token refresh with mutex pattern 
- api.ts: 401 응답 시 자동으로 refresh → retry, 동시 요청은 큐에 대기 (race condition 방지)
- auth-context.tsx: interceptor에 콜백 연결 (토큰 갱신/로그아웃)
- use-api.ts: 401 retry 로직 제거 (interceptor가 처리)
- build.sh: NEXT_PUBLIC 환경변수 검증 단계 추가
- CLAUDE.md: 프론트엔드 빌드 절차 추가

f0f7b62e3d Add Playwright headless browser as 3rd crawling fallback 
Crawl chain: Jsoup → Jina Reader → Playwright (headless Chromium).
Error page detection (403, Access Denied, etc.) triggers next fallback.
Switch to exploded classpath for Playwright driver-bundle compatibility.
Fix Next.js standalone static file serving with symlink.

0cc84354f5 Add Jina Reader API fallback for web crawling 
Jsoup fails on bot-blocked sites (403). Now tries Jsoup first,
then falls back to Jina Reader (r.jina.ai) for better coverage.
Supports optional API key via JINA_READER_API_KEY env var.
