            预编译的 Node.js ARM64 musl 二进制文件，供 ARM64 OpenWrt/iStoreOS 设备使用。

            Node.js 官方 [unofficial-builds](https://unofficial-builds.nodejs.org/) 仅提供 x64 musl 构建，不提供 ARM64 musl。
            此 Release 使用 Alpine Linux ARM64 (musl libc) 环境打包。

            **注意**: 实际 Node.js 版本可能与文件名中的版本略有差异（取决于 Alpine 仓库提供的版本），
            但主版本号 (v22.x) 保证兼容。

            `openclaw-env setup` 会在 ARM64 musl 设备上自动从此处下载。
