Customer Support Agent Demo Runner

Interactive demo showing the agent-control SDK integration.

Usage:
    python run_demo.py              # Interactive chat mode (default)
    python run_demo.py --automated  # Run automated test scenarios
    python run_demo.py --reset      # Reset agent (remove control associations) and exit

Test Commands (in interactive mode):
    /test-safe          Run safe message tests
    /test-pii           Test PII detection (if control configured)
    /test-injection     Test prompt injection detection (if control configured)
    /test-multispan     Test multi-span traces (2-3 spans per request)
    /test-tool-controls Test tool-specific controls (step_names, step_name_regex)
    /lookup <query>     Look up a customer (e.g., /lookup C001)
    /search <query>     Search knowledge base (e.g., /search refund)
    /ticket [priority]  Create a test ticket (e.g., /ticket high)
    /comprehensive      Run comprehensive support flow (multi-span)
    /help               Show available commands
    /quit               Exit the demo
