Describe the bug

Problem

Tanstack Start and @cloudflare/vite-plugin are not fully compatible with one another. For example, using virtual imports like cloudflare:workflows and cloudflare:workers causes issues; these can be marked external in vite but doing so will cause other issues during either build or deployment.

Solution

@schiller-manuel mentioned he's talking with Cloudflare to improve Tanstack Start compatibility with @cloudflare/vite-plugin.

Creating a tracking issue so we can follow progress without bugging core team for status updates in Discord.

Steps to Reproduce the Bug or Issue

..

Expected behavior

Dev should be able to add cloudflare() from @cloudflare/vite-plugin to plugins in vite.config.ts to have access to all of the miniflare environment. It should automatically prevent issues when using cloudflare virtual imports from cloudflare:workflows and cloudflare:workers. Etc.
