"""
Performance Agent
==================

Evaluates code for computational efficiency, memory usage, and scalability.
Uses radon for complexity metrics and the LLM for semantic analysis of
query patterns, I/O operations, and algorithmic efficiency.

Same architecture as SecurityAgent — inherits from BaseAgent, overrides
only agent_name, system_prompt, and run_static_analysis().
