Scripting language integration #866

Problem this feature should fix

I'm always frustrated when trying to quickly prototype gameplay mechanics or experiment with ideas in Fyrox. Since the engine currently only supports Rust for scripting and logic, iteration times are slow. The strictness of Rust, while great for production, makes it cumbersome for experimentation. This slows down the creative process, especially during early game design stages.

Expected solution

Integrate a lightweight, embedded scripting language such as Rhai, Mun, or mlua, or another similar option that allows developers to write and reload game logic at runtime without recompiling the entire project. This would significantly improve iteration speed and make Fyrox more accessible for rapid prototyping, modding, and small projects. Ideally, the scripting system should allow easy interaction with engine APIs (scene graph, input, physics, etc.) and support hot-reloading of scripts during development.
