/**
 * Swarm Task Learner
 *
 * Subscribes to SwarmTaskRunner events and saves task outcomes to MAMA DB.
 * Enables learning from task execution results to improve future decisions.
 *
 * Features:
 * - Subscribes to task-completed and task-failed events
 * - Saves task outcomes to MAMA memory for future reference
 * - Fire-and-forget pattern (non-blocking, graceful failures)
 * - Optional verbose logging
 *
