/**
 * This class represents a literal node in the stepper's AST (Abstract Syntax Tree).
 * It extends both SimpleLiteral and StepperBaseNode to integrate with the stepper system.
 * The class stores value-related properties such as type, value, raw representation,
 * and location metadata.
 *
 * @method isContractible() Indicates whether this node can be contracted (returns false).
 * @method isOneStepPossible() Indicates whether a single step evaluation is possible (returns false).
 * @method contract() Throws an error as contraction is not implemented.
 * @method oneStep() Throws an error as one-step evaluation is not implemented.
