    A basic reasoning engine to solve limited reasoning sophistication problems.
    This implementation focuses on solving logical puzzles where constraints are provided.

    Methods:
        - __init__(self, constraints: List[str]): Initialize the engine with a list of constraints.
        - add_constraint(self, constraint: str) -> None: Add a new constraint to the engine.
        - solve(self) -> Dict[str, any]: Solve the puzzle based on existing constraints and return a solution mapping.

        Add a new constraint to the engine.

        Args:
            constraint (str): A string representing a logical constraint.

This code represents a basic implementation of the `ReasoningEngine` class, which can be expanded with actual solving logic based on more sophisticated reasoning techniques.
