/* Aurora Admin —— 部署打包器（.dockerignore 是唯一真源）
 *
 * 背景（实测事故）：
 *   远端 /opt/aurora-admin 之前靠手工拷贝维护，没有 git、也没有 .dockerignore，
 *   于是 ① .design_library/aurora-admin/specs 等目录随镜像发布并对外可下载；
 *        ② 曾经修好的 nginx.conf（absolute_redirect off）被下一次拷贝覆盖丢失。
 *   本脚本把「该发什么、不该发什么」固化为可复现的一步：
 *     - 文件集只包含 docker build 真正需要的顶层条目；
 *     - 排除规则**解析 .dockerignore**（含 Docker 的匹配语义），不再维护第二份清单；
 *     - 硬断言：规范原文/agent-reports/preview/ui_kits 绝不出现，站点运行必需文件必须出现。
 *
 * 用法：
 *   node tools/pack-deploy.mjs              # 生成 dist-deploy/aurora-admin/ + manifest
 *   node tools/pack-deploy.mjs --tar        # 额外打出 dist-deploy/aurora-admin-deploy.tar.gz
