 The runtime distribution is wheel-only. The release pipeline publishes three platform wheels with the pure SDK wheel: Linux x64, Linux arm64, and macOS 14 or newer on arm64. A `python-v<repository-version>` tag is accepted only when it matches the repository version; prerelease repository versions such as `0.0.1-rc.1` use their normalized PEP 440 spelling, such as `0.0.1rc1`, inside wheel filenames and metadata.

 运行时分发包仅提供 wheel 包。发布流水线会连同纯 SDK wheel 包一起发布三个平台 wheel 包：Linux x64、Linux arm64 和 macOS 14 或更高版本的 arm64。只有与仓库版本匹配时，才接受 `python-v<repository-version>` 标签；`0.0.1-rc.1` 之类的仓库预发布版本在 wheel 包文件名和元数据中使用规范化的 PEP 440 写法，例如 `0.0.1rc1`。
