// scripts/verify-modules.js
// 铸渊 · 模块上传验证脚本
//
// 功能：
//   ① 从 SYSLOG 内容中提取模块编号（M01, M22, M-AUTH 等）
//   ② 通过 routing-map.json 查找模块对应的目录
//   ③ 检测目录是否存在于仓库中
//   ④ 检测 dev-nodes 中开发者节点是否存在
//   ⑤ 输出验证结果（JSON 格式）到 GITHUB_OUTPUT
//
// 环境变量：
//   SYSLOG_CONTENT       SYSLOG 全文内容
//   BROADCAST_ID         广播编号（如 BC-M22-009-AW）
//   AUTHOR               提交者 GitHub 用户名
