/**
 * Expo Config Plugin for `react-native-mail-engine`.
 *
 * The package is a Nitro module, so bare React Native consumers autolink it
 * without any plugin. This plugin is for **Expo (prebuild)** consumers — it
 * writes the small amount of native config a mail engine needs:
 *
 *   - **Android**: ensures `INTERNET` (and, by default, `ACCESS_NETWORK_STATE`).
 *   - **iOS**: optionally adds the `fetch` background mode (`iosBackgroundFetch`)
 *     for background refresh, and — for local development only — an App Transport
 *     Security exception (`allowInsecureNetwork`) so you can talk to a plaintext
 *     dev mail server. Android cleartext is gated behind the same flag.
 *
 * Usage in `app.json` / `app.config.ts`:
 *
 *   ["react-native-mail-engine", {
 *     "iosBackgroundFetch": false,
 *     "allowInsecureNetwork": false,
 *     "androidNetworkStatePermission": true
 *   }]
