Describe the Bug

Enabling experimental.fonts while using @astrojs/db with the Cloudflare adapter causes the build to fail during the astro:build:setup hook because source-map-js is required in a worker-like SSR context (require is not defined). Disabling fonts or removing @astrojs/db makes the build succeed.

Steps to reproduce

1. pnpm create astro@latest fonts-db-cloudflare-repro --template basics && cd fonts-db-cloudflare-repro
2. pnpm add [email protected] @astrojs/[email protected] @astrojs/[email protected]
3. Update astro.config.mjs to:

import cloudflare from '@astrojs/cloudflare';
import db from '@astrojs/db';
import { defineConfig, fontProviders } from 'astro/config';

const fonts = [
  {
    provider: fontProviders.google(),
    name: 'Doto',
    cssVariable: '--font-title',
    subsets: ['latin'],
  },
];

export default defineConfig({
  output: 'server',
  adapter: cloudflare({ imageService: 'compile' }),
  integrations: [db({ mode: 'web' })],
  experimental: { fonts },
});

What's the expected result?

Build should succeed.
