perf: optimize CI/CD pipeline - reduce execution time by 75%

**Changes:**

1. **Blazor Prerendering** (App.razor)
   - prerender: false → true
   - Eliminates white screen on page load
   - Initial HTML rendered immediately

2. **Deployment Health Check** (.gitea/workflows/deploy.yml)
   - Timeout: 120s → 60s (ATTEMPTS: 40 → 20)
   - Fail fast on deployment issues

3. **E2E Deployment Wait** (.gitea/workflows/browser-e2e.yml)
   - Timeout: 150s → 60s (retries: 30 → 20)
   - Interval: 5s → 3s between checks
   - Desktop Chrome only (skip mobile projects in CI)

4. **Playwright Optimization** (playwright.config.ts)
   - CI parallel: fullyParallel: false → true
   - Disable retries: CI retries: 1 → 0 (fail fast)
   - Allow immediate failure detection

**Expected Impact:**
- Total CI time: 60+ min → 15-25 min (-75%)
- Health check: 2 min → 1 min
- E2E tests: 4 projects → 1 project
- Explicit timeout rules at all levels

**Files:**
- playwright.config.ts: Parallel mode + no retries
- deploy.yml: 20 health check attempts (60s max)
- browser-e2e.yml: 20 deployment wait retries (60s max)
- CLAUDE.md: CI/CD optimization documented

+### CI/CD 파이프라인 최적화 (2026-06-28)
+
+**목표**: 전체 배포 시간을 최소화하고 명확한 Timeout 설정
+
+**최적화 항목**:
+
+| 항목 | 이전 | 현재 | 개선 |
+|------|------|------|------|
+| **Blazor 프리렌더링** | `prerender: false` | `prerender: true` | 흰 화면 제거 |
+| **배포 헬스 체크** | 40 × 3초 = 120초 | 20 × 3초 = 60초 | -50% |
+| **E2E 배포 대기** | 30 × 5초 = 150초 | 20 × 3초 = 60초 | -60% |
+| **Playwright 병렬** | `fullyParallel: false` | CI에서 `true` | 테스트 병렬화 |
+| **테스트 재시도** | CI에서 1회 재시도 | 재시도 없음 | 실패 즉시 감지 |
+| **E2E 프로젝트** | 4개 (Desktop/Mobile/iPad/Galaxy) | 1개 (Desktop Chrome) | -75% 테스트 |
+
+**예상 실행 시간** (정상 배포 시):
+- Build: ~3-5분
+- Test: ~1-2분  
+- Publish: ~1분
+- Deploy + Health Check: ~3-5분 (기존 2분 → 개선)
+- E2E Tests: ~5-10분 (Desktop Chrome만, 병렬 처리)
+- **전체**: ~15-25분 (기존 60분+ → -75% 단축)
+
+**Timeout 규칙**:
+- 배포 헬스 체크: 60초 (실패 시 즉시 롤백)
+- E2E 배포 대기: 60초 (실패 시 테스트 스킵)
+- Playwright 테스트: 30초/테스트 (느린 테스트는 즉시 실패)
+- Expect 조건: 10초 (느린 상호작용은 즉시 실패)
+
+**설정 파일**:
+- `.gitea/workflows/deploy.yml`: 배포 헬스 체크 60초
+- `.gitea/workflows/browser-e2e.yml`: E2E 대기 60초, Desktop Chrome만 실행
+- `playwright.config.ts`: CI에서 병렬 처리, 재시도 없음
