/**
 * Swarm Anti-Pattern Detector
 *
 * Detects repetitive failure patterns for agents before task execution.
 * Searches MAMA DB for past failures and provides warnings to prevent recurring issues.
 *
 * Features:
 * - Queries MAMA DB for agent-specific failure history (topic: swarm:{agentId}:failed)
 * - Detects patterns when failure count exceeds threshold (default: 2)
 * - Generates actionable warnings with recommendations
 * - Graceful fallback when MAMA DB unavailable
 *
 * @module swarm-anti-pattern-detector
 * @version 1.0
