Add the ability to run the server from code

[DiFuks]

We are developing an analogue of create-react-app in our company. And we want to add vitest-preview to it. There is currently no way to run the server from code.

Sample:

import { startServer } from 'vitest-preview/node';

startServer();

Hi @DiFuks. Currently, we don't have this feature available yet. We can consider to add it in the future. We will let you know if there is any update on this.
Any contributions are welcome.
