Subject: [PATCH] feat(scripts): add sync-github to mirror upstream to private
 registry

Fetch all branches and tags from upstream GitHub and force-push them to
the 192.168.0.23 private origin (full mirror). Supports DRY_RUN and an
opt-in PRUNE_BRANCHES for true mirroring.

+# sync-github: 从上游 GitHub 拉取最新源码，并全量镜像同步到 192.168.0.23 私有源。
+#
+# 默认行为（全量镜像 / 强制）：
+#   1. 确保存在 upstream remote 指向 GitHub（不存在则自动添加，URL 不一致则更新）。
+#   2. 从 upstream 抓取所有分支与 tag（--prune 清理已删除的远端引用）。
+#   3. 将上游每个分支强制推送到私有源同名分支（force push）。
+#   4. 将上游所有 tag 强制推送到私有源。
+#
+# 可用环境变量：
+#   UPSTREAM_URL     上游 GitHub 仓库地址（默认 https://github.com/gpustack/gpustack-ui.git）
+#   ORIGIN_REMOTE    私有源 remote 名称（默认 origin）
+#   UPSTREAM_REMOTE  上游 remote 名称（默认 upstream）
+#   PRUNE_BRANCHES   设为 1 时，删除私有源上「上游已不存在」的分支（真·镜像，破坏性，默认关闭）
+#   DRY_RUN          设为 1 时，仅打印将要执行的推送动作，不实际推送
+#
