/**
 * Method decorator to debounce a method call, ensuring that the function is not called more than once
 * within the specified delay. This is suitable for rate-limiting execution of handlers on
 * events that trigger very frequently such as window resize, scroll, or key press events in web applications.
 *
 * This version of debounce is designed to handle both synchronous and asynchronous methods uniformly and includes
 * comprehensive error handling to provide clear diagnostics.
 *
 * @param delay The number of milliseconds to delay; if zero or unspecified, a default of 300ms is used. The delay cannot be negative.
 * @returns MethodDecorator
