/**
 * Background Module
 *
 * Provides background task execution for non-blocking agent invocations
 * and pipeline steps. Supports concurrency control, cancellation,
 * progress tracking, and event-based notifications.
 *
 * @example
 * ```typescript
 * import { BackgroundTaskRunner } from './background/index.js';
 *
 * const runner = new BackgroundTaskRunner({ maxConcurrent: 3 }, logger);
 *
 * // Submit a background agent invocation
 * const taskId = await runner.run(
 *   'agent_invocation',
 *   'Review authentication code',
 *   async () => {
 *     return await orchestrator.executeWithFailover('reviewer', messages, options);
 *   },
 *   { role: 'reviewer', provider: 'openai' }
 * );
 *
 * // Check status later
 * const task = runner.getTask(taskId);
 *
 * // Or wait for completion
 * const completed = await runner.waitFor(taskId, 60000);
 * ```
