CI / build (push) Failing after 11s
- 新增 dashboard.c / dashboard.h，提供自包含 HTML 管理面板 - 复用现有 SSE 基础设施（sse.c/sse.h）实现实时指标推送 - 每 2 秒推送 JSON 指标（uptime/connections/requests/2xx/3xx/4xx/5xx），每 6 秒心跳 - 端点：/_status（HTML 面板）、/_status/events（SSE 指标流） - 将 server.c 中的统计变量改为全局可见，供 dashboard 访问 - 新增 9 个单元测试覆盖 dashboard_handle_request / dashboard_handle_events - 编译零警告，474 单元测试 + 111 集成测试通过 （4 个集成测试失败为既有反向代理环境问题，与本次改动无关）
