📚 Description

This PR avoids modifying the URL for vite middleware injected prior to viteTransformMiddleware, instead injecting another middleware to make the modification within the vite stack.

The underlying mechanism of skipping the vite transform hasn't changed, just the time of making the change.

For reference, the function name viteTransformMiddleware is part of Vite's public API and won't be changed except for a breaking change in a Major.
