feat!: support latest React Native versions

[jokerttu]

Fixes compatibility issues with the latest React Native versions on Android.

• Updated communication bridge implementation for Android.
• Bumped example app and package RN version to 0.81.1.

Note: This PR upgrades the example app to the latest React Native version, which breaks Detox support on Android. To run Android Detox tests, the example app must first be downgraded to React Native 0.79.5 until support for newer versions is available.

Fixes #437
