【OpenHarmony】【weex】当前Weex框架，没有鸿蒙SDK版本，请问我们能否在weex仓库新增一套集成到鸿蒙的能力？

当前flutter，rn，taro等跨平台框架都在适配openharmony系统平台，希望weex也能适配openharmony系统，是否可以在仓库目录下建一个ohos目录，合入openharmony适配层的代码和文档说明，不改动weex本身的代码和架构。

Review the repository structure and its existing platform integration areas, then assess the proposed ohos directory for an OpenHarmony adaptation layer and documentation. Done means there is agreement on the integration design and scope, with working adaptation code and documentation that do not change Weex’s existing code or architecture.
