Trixy Network System Demonstration

This script demonstrates the complete network protocol and command system
implementation for the Trixy voice assistant system.

Features demonstrated:
1. Custom Trixy Protocol with binary message format
2. Hard-coded performance commands (TRXINOOP, TRXIPING, etc.)
3. Command classes for satellite management
4. Server and client socket handling
5. Event system integration
6. Multi-socket architecture

Usage:
    python3 network_demo.py
