feat(k8s): 完整 K8s 管理能力 — 日志/exec/扩缩容/HPA/CronJob/CI webhook
新增功能: - Pod 日志查看 (GET logs, 支持 tail/container 参数) - Pod exec 命令执行 (文件浏览 ls/cat/stat) - Deployment 副本数加减 (scale PATCH) - Deployment 滚动重启 (restart annotation) - Deployment CI webhook (update-image, 滚动更新镜像) - HPA 管理: 列表/创建(CPU+内存指标)/删除 - CronJob 管理: 列表/创建/暂停恢复/手动触发/删除 - Namespace 列表 K8s Client 扩展 (纯标准库, 零外部依赖): - 新增 post/patch/delete HTTP 方法 - GetPodLogs/ScaleDeployment/UpdateDeploymentImage/RestartDeployment - ExecInPod/ListHPAs/CreateHPA/DeleteHPA - ListCronJobs/CreateCronJob/SuspendCronJob/DeleteCronJob/TriggerCronJob - ListNamespaces 已知限制: Exec SPDY 交互终端需引入 remotecommand 包
