[Feature] ability to load multiple featureApps from separate host/sub-domain

[akhilshastri]

usecase - for an enterprise application, different teams building domain specific features, if it's a one SPA - then it needs to bundle together hence a whole release cycle is require - which is costly.

if we could split the entire application in small mini-apps and load as one single app at runtime then every team can have separate individual builds/release - hence smaller release and QA only for mini-app.

Webpack 5 has module-federation which something similar but it bundles dependency ahead of time hence larger bundle size or not suitable for Server side rendering or for React Server Components.

Can we build a better solution with Vinxi (may be a vite plugin - which further can useful to other framework..?)
