 * Queue Manager - Manages BullMQ queues for different component types

 * - Collector queue: High priority, fast execution for data collection
 * - Harvester queue: Medium priority, slower processing for data transformation
 * - Priority queue: Urgent/manual jobs with highest priority
 *
 * @example
 * ```typescript
 * const queueManager = new QueueManager({
 *   redis: { host: 'localhost', port: 6379 },
 *   collectorWorkers: 3,
 *   harvesterWorkers: 2
 * })
 *
 * await queueManager.close()
