CJS dependencies cause fatal issues when building/running that go unnoticed in dev mode

[CAYdenberg]

Reproduction is here: https://github.com/CAYdenberg/fresh-2-cjs-build-repro

• deno task dev - works
• deno task build then deno task start - does not work, results in

error: Uncaught (in promise) ReferenceError: Cannot access '_default$i' before initialization
const Range$2 = __require$g ?? _default$i ?? _mod$2;

Also, resetting to the initial commit or commenting out the use of Sharp will result in a successful build.

The issue probably stems from Sharp being written in CJS. Still, it would be awesome if deno install or Fresh or the Fresh vite plugin could issue a warning when encountering CJS, as it is very difficult to debug when a project is working fine in development mode and then fails at the very last step.

I tried to replicate it with svelte-kit + vite + deno + sharp, but for some reason this worked flawlessly. So maybe it's somehow related to @fresh/plugin-vite?

I mean, it's going to come down to the order things are bundled in. So trying to reproduce it in a different context doesn't tell us much.
