MiFaZhan 2ed5dfa6a1 chore: 初始开源发布
iotlcm-app:小程序端 + 用户端服务。

- app/:uni-app 小程序前端(基于 unibest,MIT)
  - 微信 AppID → YOUR_WX_APPID,uni-app AppID → __UNI__YOURAPPID
  - 内网后端地址 → admin.iotlcm.example.com
  - 应用标题与 unibest 模板 README 重写(保留上游致谢与 MIT 声明)
- server/:GoFrame 用户端服务(基于 XiuAdmin,Apache-2.0)
  - module xiuadmin → git.5iot.com/iotlcm-public/iotlcm-app(360 文件)
  - 支付回调地址 → app.iotlcm.example.com,商户名与应用名泛化
  - 真实手机号 → 合法 11 位编造号(保留号段前 3 位 + 后 4 位)
  - 依赖号码尾部的断言同步更新
  - 补 server/LICENSE(Apache-2.0)
- 移除内部资产:CI 触发器
- 补根 README,LF 行尾 + .gitattributes

已知:TestSysDept_RefreshDeptAncestors 在源仓同一提交上同样失败,属既有缺陷。
