/**
 * Event Bus Module
 * 
 * Provides centralized event system for cross-module communication.
 * 
 * Usage:
 * - Add data-module="event-bus" to enable global event bus
 * - Or import and use directly: import { EventBus } from './modules/event-bus/index.js'
 * 
 * Features:
 * - Pub/sub pattern
 * - Namespaced events
 * - Event filtering
 * - Event history
 * - Integration with LiveComponents
 * - Integration with SSE
