FINAL WORKING EXAMPLE: Real Swarms API MCP with Streaming

This is THE ONE example that actually works and demonstrates:
1. Real Swarms API integration with streaming
2. Cost-effective models (gpt-3.5-turbo, claude-3-haiku)
3. Multiple transport types (STDIO, HTTP, Streamable HTTP, SSE)
4. Auto-detection of transport types
5. Live streaming output with progress tracking

RUN THIS: python examples/mcp/final_working_example.py

REQUIRES: SWARMS_API_KEY in .env file
