Contributions summary:Rafael primarily contributed to the `compose-destinations` library, focusing on enhancing navigation functionality for Jetpack Compose applications. Their work involved adding support for custom type serializers, which included modifying the code generation process, introducing new templates for custom navigation types, and integrating the kotlinx-serialization library for serialization/deserialization. These changes enable developers to pass custom data types as navigation arguments in a type-safe manner. Furthermore, they added sample code to demonstrate how to use the new features.
