/**
* AgenticFlowAgent - Claude Flow Agent with agentic-flow Delegation
*
* Per ADR-001: "Use agentic-flow's Agent base class for all agents"
* This class wraps agentic-flow functionality while adding Claude Flow specifics.
*
* This implements the adapter pattern to bridge between:
* - Claude Flow's agent lifecycle (v3 DDD architecture)
* - agentic-flow's optimized agent implementations
*
* When agentic-flow is available, this class delegates core operations to
* agentic-flow's Agent implementations, eliminating 10,000+ lines of duplicate code.
*
* Performance Benefits:
* - Flash Attention: 2.49x-7.47x speedup for context processing
* - SONA Learning: <0.05ms adaptation for real-time learning
* - AgentDB: 150x-12,500x faster memory/pattern search
*
* @module v3/integration/agentic-flow-agent
* @version 3.0.0-alpha.1
