/**
 * Debounce decorator to debounce method calls in Temporal workflows.
 *
 * This decorator uses Temporal's CancellationScope to implement debouncing:
 * - When a decorated method is called multiple times in quick succession, only the last call executes
 * - Previous pending calls are cancelled via CancellationScope
 * - The method execution is protected from cancellation using nonCancellable scope
 *
 * The implementation acts as an async mutex by:
 * - Tracking the current execution via the currentScope variable
 * - Cancelling any in-progress debounce wait period when a new call arrives
 * - Ensuring the actual method execution happens in a non-cancellable context
 * - Properly handling cancellation exceptions
 *
 * @param {number} ms - The debounce time in milliseconds.
 * @returns {MethodDecorator} - The debounce decorator.
