/**
 * Creates a local event broker configured with domain event handlers.
 *
 * The broker automatically wires each handler to its source topic and propagates
 * resulting events. Includes default error handling with console logging.
 *
 * @param eventHandlers - Array of event handlers to register with the broker
 * @param options - Configuration options
 * @param options.onError - Custom error handler for broker errors
 * @param options.onDomainedEvents - Callback for handling domain-specific events
 * @returns Configured SimpleEventBroker instance with handlers subscribed
 *
 * @example
 * ```typescript
 * const broker = createSimpleEventBroker([
 *   createArvoOrchestrator(...),
 *   createArvoEventHandler(...)
 * ]);
 *
 * await broker.publish(createArvoEvent({
 *    type: 'com.openai.completion',
 *    data: {...}
 * }));
 * ```
