ggen 1.2.0

//! Agent Orchestration System - Ultra-Advanced Multi-Agent Coordination
//!
//! This module orchestrates the 12 hyper-specialized agents, managing their
//! lifecycle, coordinating their interactions, and ensuring optimal performance
//! across the entire ggen ecosystem.
//!
//! # Orchestration Architecture
//!
//! ## Core Orchestration Features
//!
//! - **Agent Lifecycle Management**: Spawn, monitor, and terminate agents
//! - **Task Distribution**: Intelligent workload distribution based on agent capabilities
//! - **Performance Monitoring**: Real-time monitoring of agent health and performance
//! - **Fault Recovery**: Automatic recovery from agent failures using Byzantine protocols
//! - **Knowledge Integration**: Seamless sharing of knowledge across agents
//!
//! ## 80/20 Principle Implementation
//!
//! - **20% Core Agents**: london-bdd, byzantene, quantum-optimizer, semantic-analyst
//! - **80% Specialized Agents**: market-intelligence, security-sentinel, etc.
//! - **Hyper-Optimization**: Each agent focuses on 20% of features providing 80% of value
