fix: harden G14 CI dependency diagnostics

 - 默认 GitOps 生成分支是 `G14-gitops`；Pipeline 成功后把本次 source commit 对应的 `deploy/gitops/g14/**` 推送到该分支，避免把生成提交继续写回 `G14`。
 - 默认 registry prefix 是 `127.0.0.1:5000/hwlab`，用于 G14 单节点 k3s 的 node-local registry。
 - 默认 CI/CD proxy 是 G14 本机 `http://127.0.0.1:10808` / `socks5h://127.0.0.1:10808`。Tekton CI step、Docker-in-Docker sidecar 和 publish step 都注入 proxy/no_proxy；publish step 必须先在 DIND 内 `docker pull $HWLAB_DEV_BASE_IMAGE`，再进入 DEV base-image preflight、build 和 registry push，保证 npm、Playwright Chromium 安装、base image 拉取和 registry push 走 G14 本机代理边界。CI step 固定使用 Node 22 Debian 镜像，避免 Playwright 官方镜像内 Node 版本漂移影响 `node --test`。
+- 任何依赖下载阶段都必须有可观测诊断。生成的 Tekton 脚本在 apt/apk、npm、Playwright browser、Docker base image pull 和 GitOps promote 之前输出结构化 `dependency-proxy-probe`、`dependency-curl-probe` 或 `dependency-download-*` 日志，至少包含 phase、目标 URL/镜像、脱敏 proxy、首包耗时、总耗时、下载字节数和速度。CI/CD 卡在下载时，先用这些日志判断是 proxy 不可达、目标源慢、DNS/首包慢还是下载吞吐低，再决定是否切换 G14 代理节点或预热镜像；不能只凭 PipelineRun Running 时长判断业务测试失败。

 Pipeline 的标准路径是：`G14` source commit -> `CI.json` Tekton 测试 -> commit-tagged image push 到 G14 registry -> render `deploy/gitops/g14/**` -> push `G14-gitops` -> Argo CD 同步 runtime。CD 只消费已经构建好的镜像和 Git desired state，不在 Argo CD 内构建镜像。

+
+如果 probe 显示 `proxy-env-missing`、`proxy-connect-failed`、`timeout` 或速度长期接近 0，应先按 `/root/docs/vpn-proxy-ops.md` 检查 v2rayN/Hysteria，再重跑 polling。若 probe 正常但后续测试失败，按对应 `CI.json` 命令和业务检查排障。
