Module dispatch 

Function dispatch for expression evaluation

Contains the performance-critical function dispatch table that routes function calls to their implementations.

This module provides:

• evaluate_function_dispatch() - O(1) dispatch via compiler jump table
• evaluate_orthogonal_polynomial() - helper for orthogonal polynomial evaluation

Functions
