Live Speed Optimization Demonstration for MaverickMCP Research Agent

This script validates the speed improvements through live API testing across
different research scenarios with actual performance metrics.

Demonstrates:
- Emergency research (<30s timeout)
- Simple research queries
- Model selection efficiency (Gemini 2.5 Flash for speed)
- Search provider performance
- Token generation speeds
- 2-3x speed improvement validation
