Adds Auth0 authentication to Expo apps using the react-native-auth0 SDK with proper native iOS and Android configuration. Handles the full setup: Expo config plugin integration, custom URL schemes, callback configuration, and the Auth0Provider wrapper with login/logout hooks. One thing to know upfront: this only works with custom development builds or EAS, not Expo Go, because it needs native modules. The skill includes automated build verification and will bail after a few failed attempts rather than spinning forever. Good choice if you're on Expo SDK 53+ and need managed authentication. For bare React Native CLI projects, you want auth0-react-native instead.
