Describe the Bug

Steps to reproduce

• Run npm create cloudflare@latest cloudflare-astro -- --framework=astro.
• astro.config.mjs:

import { defineConfig } from "astro/config";
import cloudflare from "@astrojs/cloudflare";

// https://astro.build/config
export default defineConfig({
  output: "hybrid",
  adapter: cloudflare({
    imageService: "compile",
    platformProxy: {
      enabled: true
    }
  })
});

• src/pages/index.astro:

---
import Layout from '../layouts/Layout.astro'

import { Image } from 'astro:assets'
---

<Layout title="Welcome to Astro.">
  <main>
    <Image
      src={import('../assets/image.jpg')}
      widths={[250, 500]}
      sizes="250px"
      alt=""
      style="width: 250px; height: auto"
    />
  </main>
</Layout>

• Add an image src/assets/image.jpg.
• Run npm preview.

This should build the project and then execute wrangler pages dev.

Expected behavior

There should be no errors, as everything works as expected when deploying to Cloudflare Pages.

Observed behavior

wrangler pages dev fails with the errors below.

node_modules/detect-libc is a dependency of the sharp library to optimize the images on build. With output: "hybrid" and imageService: "compile" the images are only optimaized for the static pages at build time and the sharp library is never used in SSR.

✘ [ERROR] Could not resolve "child_process"

The package "child_process" wasn't found on the file system but is built into node. Add "node_compat = true" to your wrangler.toml file and make sure to prefix the module name with "node:" to enable Node.js compatibility.

Running into the same problem - was able to workaround by moving the built (e.g. with astro, ./dist/*) directory subtree into a separate parent directory that doesn't include package.json or node_modules. It appears that even though wrangler is being told to just serve the contents of DIRECTORY it still looks into the parents and complains/fails about things it finds in node_modules that are incompatible with the CF runtime.
