[LarsWerkman]

This PR introduces Kotlin bindings for the Zen Rules Engine, leveraging Mozilla's UniFFI project to generate the necessary interop code. These bindings are designed to make it easier for Kotlin developers to integrate and utilize the Zen Rules Engine in their applications.

Key Features

• UniFFI Integration: Utilizes UniFFI to generate Kotlin bindings, ensuring consistency with existing language support.
• Core Functionality: Provides seamless access to the Zen Rules Engine API in Kotlin.
• Gradle Integration: Initial setup of the Gradle build system to handle Kotlin target compilation.

Current Progress

• Kotlin bindings generated and validated for functionality.
• Basic integration tests to ensure bindings are functioning as expected.
• Initial documentation for Kotlin developers.

TODOs

• Maven Repository Setup: Complete configuration to publish the bindings to a Maven repository for distribution.
• Basic integration tests to ensure bindings are functioning as expected. (have been done manually for now)
• Documentation Expansion: Improve documentation, including usage examples, to facilitate easier adoption by developers.

Impact

This PR enables Kotlin developers to seamlessly integrate the Zen Rules Engine into their applications.
