This plugin modifies your Android app to use Cronet as the HTTP client:
1. Adds Cronet dependencies to build.gradle
2. Initializes in MainApplication.onCreate()
3. Sets a custom that uses Cronet
All network requests made via fetch() (both React Native's built-in and expo/fetch`) will automatically use Cronet.
- Expo SDK 52+
- Android only (iOS not supported, uses native networking)
