Rainer Friederich opened merge request !74: Add server component exports at project / next_webform

This PR does the following:

Change build to tsup (like next-drupal)

Add additional entry point (server)

Add server only exports to the server entry point

Keep client exports on the index entry point for BC reasons

Adjust api route to new app router next object.

Add example project using app router

duplicate cypress tests for now (simplictiy to get first review)

I would like to get a review on the direction and the wanted style of this. We could also deprecate pages router and tag a 2.0 with only the app router items.

The current changes would allow for a 1.2.0 release
