/**
 * Fast-Fallback Workflow Configuration
 *
 * Uses layer-based execution with sequential groups:
 * 1. Fast tier: GPT-4o-mini (try first)
 * 2. Mid tier: Gemini 2.0 Flash (if fast fails)
 * 3. Premium tier: GPT-4o or Claude 3.5 Sonnet (last resort)
 *
 * Each group runs sequentially - only proceeds if previous fails
 *
 * @example
 * ```typescript
 * import { runWorkflow } from '../core/workflowRunner.js';
 * import { FAST_FALLBACK_WORKFLOW } from './fallbackWorkflow.js';
 *
 * const result = await runWorkflow(FAST_FALLBACK_WORKFLOW, {
 *   prompt: 'What is 2+2?',
 *   verbose: true,
 * });
 *
 * // Usually completes with fast tier, saving cost
 * console.log('Executed models:', result.ensembleResponses.length);
 * ```

 * More aggressive fallback with parallel premium tier:

 *
 * Guarantees high quality if fast tier fails
