C3 used with npm doesn't produce working SolidStart projects (due to `unenv/node/internal/*` errors)

Describe the Bug

If I use create-cloudflare to create a SolidStart project via npm (specifically npm create cloudflare -- --platform=workers --framework=solid my-solid-app) the resulting project builds fine but then it can't be previewed via wrangler dev nor deployed via wrangler deploy as those commands cause the following errors:

(Note: there are lots of other warnings but those don't seem to break the app)

See:

npm-c3-solid.mp4

---

This issue does not seem present when using pnpm instead, see:

pnpm-c3-solid.mp4

Please provide any relevant error logs

No response

It works on my machine using the latest c3:

npm create cloudflare@latest -- --platform=workers --framework=solid my-solid-app

Hard to investigate more without the version of c3 / a repro

Edit: there are build warnings but the demo works fine

Discussed offline. This is because when C3 installs packages via npm it uses --legacy-peer-deps, which doesn't correctly layout the unenv dependencies (there are v1 and v2 dependencies referenced) in the node_modules directory.
This results in the esbuild bundling step trying to load from the wrong version.
