🧠 UNIVERSAL AI BRAIN 3.3 - The world's most advanced cognitive architecture with 24 specialized systems, MongoDB 8.1 $rankFusion hybrid search, latest Voyage 3.5 embeddings, and framework-agnostic design. Works with Mastra, Vercel AI, LangChain, OpenAI A

/**
 * @file AttentionManagementSystem.test.ts - Comprehensive tests for real-time attention management
 * 
 * Tests the AttentionManagementSystem's ability to:
 * - Manage real-time attention allocation with change streams
 * - Monitor cognitive load and trigger alerts
 * - Handle priority queue management for tasks
 * - Filter distractions and protect focus
 * - Analyze attention patterns using MongoDB aggregation
 * - Provide real-time monitoring and optimization
