This commit refactors the type checking logic for functions and operators to improve type safety and expressiveness. Key changes include: - Introduced `StaticType::FunctionOverloads` to represent functions with multiple possible signatures, enabling better handling of operator overloading. - Updated the `TypeChecker` to correctly infer function types and resolve calls with overloaded functions. - Modified the `Environment` to register standard library functions with specific `FunctionOverloads` signatures, replacing the previous `StaticType::Any` approach. - Enhanced the `StaticType::resolve_call` method to intelligently match argument types against expected parameters, including handling of overloaded functions. - Added new tests to verify the correctness of type inference for lambda returns and operator overloading.
