Module evaluation 

Expression evaluation methods

This module contains the evaluation logic for expressions, including:

• evaluate() method with domain checking
• evaluate_with_context() method for variable substitution
• evaluate_to_f64() method for numerical conversion
• substitute() method for variable replacement
• Hardcoded function dispatch for performance

Module Organization

• core: Main evaluation methods (evaluate, evaluate_with_context, evaluate_to_f64)
• substitution: Variable substitution (substitute)
• dispatch: Performance-critical function dispatch table

Re-exports

pub use dispatch::evaluate_function_dispatch;
