/**
 * Multi-Agent Handler Utilities
 *
 * Provides a simple helper to create handlers with content aggregation for multi-agent scripts.
 *
 * Usage:
 * ```typescript
 * const { contentParts, aggregateContent, handlers } = createHandlers();
 *
 * // With callbacks
 * const { contentParts, aggregateContent, handlers } = createHandlers({
 *   onRunStep: (event, data) => console.log('Step:', data),
 *   onRunStepCompleted: (event, data) => console.log('Completed:', data)
 * });
 * ```
