Implement Term and Variable types for fuzzy logic

Added Term wrapper for membership functions and Variable type for crisp domains with named fuzzy terms. Implemented insertion, lookup, and evaluation logic with error handling. Added prelude module for convenient re-exports. Improved formatting and error handling in membership functions. Includes comprehensive unit tests for new types.
