/**
 * Simple event manager for handling event listeners and dispatching events.
 *
 * Provides a lightweight alternative to the more complex AcCmEventDispatcher
 * for cases where you need basic event handling with type-safe payloads.
 *
 * @template T - The type of the event payload.
 *
 * @example
 * ```typescript
 * // Create an event manager for string payloads
 * const manager = new AcCmEventManager<string>()
 *
 * // Add a listener
 * manager.addEventListener((message) => {
 *   console.log('Received:', message)
 * })
 *
 * // Dispatch an event
 * manager.dispatch('Hello, World!')
 *
 * // For complex payloads
 * interface LoadEvent {
 *   url: string
 *   progress: number
 * }
 *
 * const loadManager = new AcCmEventManager<LoadEvent>()
 * loadManager.addEventListener(({ url, progress }) => {
 *   console.log(`Loading ${url}: ${progress}%`)
 * })
 * ```
