Comprehensive Autonomous Multi-Agent Demo

Demonstrates Claude Code-style autonomous capabilities:
1. Multi-Agent Coordination (RAG → CodeGen → ReAct)
2. Real Tool Execution (file ops, bash, web search)
3. Objective Convergence Detection (while(tool_call_exists))
4. Multi-Cycle Autonomous Operation
5. Tool Chaining and Feedback Loops

Scenario:
  Create a Python data processing script autonomously:
  - Phase 1: Research best practices (RAGResearchAgent with tools)
  - Phase 2: Generate implementation (CodeGenerationAgent with tools)
  - Phase 3: Test and validate (ReActAgent with tools)

Requirements:
- OPENAI_API_KEY in environment
- Uses GPT-3.5-turbo for real inference
- Real file system operations
- NO mocking, simulation, or hardcoding
