- 添加 /health/live 存活探针别名(原 /health + /health/ready 保留)
- 新增 metrics middleware:http_requests_total 计数器 + http_request_duration_seconds 直方图
- Prometheus exporter 独立端口 9090(可通过 ERP__SERVER__METRICS_PORT 覆盖)
- 后台任务每 30s 采样 DB 连接池活跃/空闲连接数(pg_stat_activity)
- 后台任务每 30s 采样 EventBus pending 事件积压数
- UUID 路径归一化避免高基数(/api/v1/users/:id/posts)
