Agent ROS Bridge - Full Demonstration

This script demonstrates the complete flow:
1. Agent receives natural language command
2. Agent parses intent using AI
3. Agent reasons about execution
4. Bridge sends commands to ROS
5. Robot executes in simulation

Usage:
    python examples/full_demo.py

Requirements:
    - ROS2 Docker container running: docker start ros2_humble
    - Agent ROS Bridge installed
