feat(sandbox): add CustomSandbox to module exports

Add CustomSandbox class to the sandbox module's exports to make it available
for import and use in other parts of the application.

This enables users to utilize the custom sandbox functionality that was
previously not exposed through the main module interface.

feat(sandbox): 添加 CustomSandbox 到模块导出

将 CustomSandbox 类添加到 sandbox 模块的导出中，使其可在应用程序的其他部分导入和使用。

这使用户能够利用以前未通过主模块接口公开的自定义沙箱功能。
