feat(P2): 实现质量保障类5项功能(无障碍/视觉回归/通知渠道/漏洞扫描/灾备)
## 新增功能 ### 1. 屏幕阅读器兼容性增强（a11y） - 无障碍工具库：src/shared/lib/a11y.ts - aria-live Hook：src/shared/hooks/use-aria-live.ts - a11y 组件：skip-link/visually-hidden/focus-trap/aria-status - 增强 UI：table.tsx 系统性 ARIA role，dialog.tsx aria-modal - 审计文档：docs/accessibility/a11y-audit.md（WCAG 2.1 AA 清单） ### 2. 视觉回归测试 - 测试套件：tests/visual/（homepage + 3 个 dashboard） - 3 视口（desktop/tablet/mobile）× 2 主题（light/dark） - 动态元素遮罩，避免误报 - playwright.config.ts 新增 visual-chromium 项目 - 文档：docs/testing/visual-regression.md ### 3. 短信/微信推送渠道集成 - 新模块：src/modules/notifications/ - 4 个渠道：SMS（阿里云/腾讯云）、WeChat（公众号）、Email（SMTP）、In-App - 分发器按用户偏好并行多渠道发送 - 外部 SDK 动态 import，Mock 模式开发可用 - 文档：docs/notifications/channels.md ### 4. 漏洞扫描 CI 集成 - CI security-scan job：npm audit + Snyk + Trivy FS + OWASP ZAP - 独立工作流 security.yml：每周一深度扫描 + 容器镜像扫描 - 配置：suppressions.json + .trivyignore - 本地脚本：security-scan.sh/ps1 - 文档：docs/security/scanning.md（SLA 分级） ### 5. 灾备方案 - 脚本：backup-verify/backup-offsite-sync/dr-drill/failover/health-check - CI 增强：备份后校验+异地同步，每周灾备演练 - 独立工作流 dr-drill.yml：每周一凌晨 4 点自动演练 - 文档：docs/dr/dr-plan.md（RTO 4h/RPO 24h）+ dr-runbook.md（6 故障场景） ## 验证 - npx tsc --noEmit：0 错误 - npm run lint：0 错误 0 警告
