@copilot Let's make it a bit backward compatible to maybe react native 0.80 if possible supporting the latest arch. For iOS, we aim to support at least ios 15.

Updated to support React Native 0.80+ with backward compatibility while maintaining the latest architecture support. iOS minimum deployment target remains at 15.0 as requested. The library now works with RN 0.80 through 0.83+ using modern tooling (Kotlin 2.1 KTS, Swift 6.0).
