Describe the Bug

Observed behavior

Importing packages with workerd runtime key from globalSetup fails.

I tried to use Postgres.js from a globalSetup file to run database migration, but this error was raised.

Error: Only URLs with a scheme in: file, data, and node are supported by the default ESM loader. Received protocol 'cloudflare:'

This is because

vitest-pool-workers set workerd as one of resolve.conditions of vite config
globalSetup is executed by Node.js, but Postgres.js has workerd key in its export field, so the file for workerd runtime is loaded

As proof of that, if you add this setting to your vitest config, globalSetup works

    ssr: {
        resolve: {
            conditions: ['import']
        }
    }

However, then, tests using Postgres.js fail

 FAIL  test/index.spec.ts [ test/index.spec.ts ]
Error: No such module "Users/xxx/repro-vitest-pool-workers-import-error/node_modules/.pnpm/postgres@3.4.4/node_modules/postgres/src/os".
  imported from "Users/xxx/repro-vitest-pool-workers-import-error/node_modules/.pnpm/postgres@3.4.4/node_modules/postgres/src/index.js"

I guess this is because resolve condition is no longer workerd. Vitest is trying to import files for runtime other than workerd.

Expected behavior

You can import postgres correctly

Steps to reproduce

Please provide the following:

run npm create cloudflare@latest and select Hello World example and then Hello World Worker
