Hi, this is not correct because Solathon does not have ComputeBudgetProgram class anywhere. The purpose of the issue was to introduce this class for people to be able to utilize it. You just added documentation for something that doesn't exist yet.

Hi! Sorry about that I misunderstood the purpose of the issue. I now realize that the ComputeBudgetProgram class doesn’t exist yet and the goal is to implement it, not just add documentation for it.

I have now implemented the ComputeBudgetProgram class in the core library as requested, including both set_compute_unit_limit and set_compute_unit_price methods. Unit tests have also been added to cover these new methods. The documentation and usage examples now accurately reflect the current implementation.

Please take a look at the updated PR when you have a chance. Let me know if any further changes are needed! make this short and simple
