Some checks failed
Build and Deploy Backend / build-and-deploy (push) Failing after 4m28s
## 变更内容
### k8s/ingress.yaml
- 新增 /xiaozhi/v1/ 路径规则，将 WebSocket 流量路由到 hw-ws-svc:8888
- Traefik 最长前缀优先，/xiaozhi/v1/ 不影响 / 下的 Django 路由
### hw_service_go/k8s/service.yaml
- Service 类型由 LoadBalancer 改为 ClusterIP
- 移除阿里云 SLB 注解（通过 Traefik Ingress 统一暴露，不再需要独立公网 IP）
### hw_service_go/k8s/deployment.yaml
- 镜像地址改为 ${CI_REGISTRY_IMAGE}/hw-ws-service:latest 占位符
- CI/CD 部署时统一通过 sed 替换为华为云 SWR 实际地址
### hw_service_go/internal/server/server.go
- 新增 GET /xiaozhi/v1/healthz 接口，返回 {"status":"ok","active_connections":N}
- 用于部署后验证服务存活及当前连接数
### .gitea/workflows/deploy.yaml
- 新增 Build and Push HW WebSocket Service 步骤，构建并推送 hw_service_go 镜像
- 部署步骤新增 kubectl apply hw_service_go/k8s/deployment.yaml 和 service.yaml
- 新增 kubectl rollout restart deployment/hw-ws-service
### run.sh
- 本地同时启动 Django + hw_service_go 的开发脚本
