[🐞] Vite error @qwik-router-not-found-path when migrating to v2

[steffanek]

Which component is affected?

Qwik Runtime

Describe the bug

I've tried to migrate to v2 manually and I have a common qwik file to store qwik related function, components and types.
When importing for example Slot from this common file, I've noticed a vite error.
See the repro in src > routes > layout.tsx where I explicitly do: import { Slot } from '~/common/qwik';

Additional Information

As discussed today @wmertens, my feeling was right about the common/qwik causing it.

[wmertens]

The reason the build failed was the re-exporting of the vite plugins in common/qwik.ts

Removing those as well as the node middleware makes the build work.

However, when re-exporting a xyz$ function, the corresponding xyzQrl function must also be exported. Furthermore, you can't re-export $, it's special and must be imported from the Qwik core library.

We recommend not re-exporting qwik functions.

@steffanek We should document that, would you like to contribute with a docs PR?
I think the right place could be here in the build/v2/ branch. Thanks in advance 🚀
