PluginError: Cannot find module '@expo/config-plugins' on prebuild

[finleyaa]

Bug report

Summary

When using the package with Expo SDK 56, it seems that the Expo CLI runs into an issue with @expo/config-plugins. The package is not hoisted to the project root node_modules, so module resolution fails.

Related: react-native-maps/react-native-maps#5927 (comment)

Steps to reproduce

1. Create an Expo SDK 56 project (or upgrade an existing one)
2. Install datetimepicker: npx expo install @react-native-community/datetimepicker
3. Enable the config plugin in app.config.ts
4. Run npx expo prebuild and get error:

PluginError: Cannot find module '@expo/config-plugins'
Require stack:
- node_modules/@react-native-community/datetimepicker/plugin/build/withDateTimePickerStyles.js
- node_modules/@react-native-community/datetimepicker/app.plugin.js
- node_modules/expo/node_modules/@expo/require-utils/build/load.js
- node_modules/expo/node_modules/@expo/require-utils/build/index.js
- node_modules/expo/node_modules/@expo/config/build/Config.js
- node_modules/expo/node_modules/@expo/config/build/index.js
- node_modules/expo/node_modules/@expo/cli/build/src/start/detectDevClient.js
- node_modules/expo/node_modules/@expo/cli/build/src/start/resolveOptions.js

Describe what you expected to happen:

Prebuild should succeed without requiring @expo/config-plugins as a direct project dependency.
