AutoGen Agent Setup & Roles

Set up your AutoGen environment with three agents: 'Lead Developer' (initiates tasks, provides initial code), 'Code Reviewer' (critiques code, suggests improvements), and 'Performance Tester' (executes code, measures metrics). Assign Gemini 3 (or Gemini 2.5 Pro) as the core LLM for each. Define their initial system messages and responsibilities.
