    统一构建管理：依赖拉取 → 编译 → 安装 / 测试。

    用法:
        python build.py                             完整构建（拉取依赖 + Release 编译）
        python build.py local                       本地构建（跳过依赖拉取, Release 编译）
        python build.py test                        单元测试（拉取依赖 + Debug 编译 + 执行测试）
        python build.py test local                  单元测试（跳过依赖拉取, Debug 编译 + 执行测试）
        python build.py --version/-v <version>      指定构建版本号（用于 run/exe/dmg 包）
        python build.py --extra/-e KEY=VALUE        指定额外构建选项，可多次使用

    参数说明:
        - 参数: command    : 构建动作: 为空时为全构建, local 为跳过依赖下载, test 为运行单元测试。
        - 参数: --version  : 构建版本号，不传时默认 1.0.0。
        - 参数: --extra    : 额外构建选项，格式为 KEY=VALUE，可多次指定。
