将 handlers/kubernetes.go (4204行/134函数) 按业务域拆分为: - kubernetes.go (106L): struct + constructor + 共享helpers - k8s_cluster.go (642L): 集群CRUD + 同步 + RBAC - k8s_workload.go (696L): Deployment/STS/DS/ReplicaSet操作 - k8s_pod.go (653L): Pod日志/终端/exec/指标 - k8s_pod_files.go (206L): Pod文件浏览/上传/下载 - k8s_resource.go (351L): Service/Ingress/ConfigMap/Secret/PVC/Topology - k8s_hpa_cronjob.go (384L): HPA + CronJob - k8s_yaml.go (213L): YAML get/update/delete/apply - k8s_namespace.go (305L): Namespace CRUD - k8s_events.go (207L): 事件列表+聚合 - k8s_node.go (428L): Node详情+资源分配 - k8s_compare.go (146L): 多集群对比 验收: go build零错误, 425条路由不变, 26个K8s API端点回归测试全通过
