Tenuo × AgentQL Demo with REAL LLM

Shows both simple and advanced attack scenarios:
- Simple: Direct prompt injection (quick demo)
- Advanced: Indirect injection, social engineering, helpfulness exploitation

Requirements:
    uv pip install openai  # or anthropic

Usage:
    export OPENAI_API_KEY="your-key"
    export AGENTQL_API_KEY="your-agentql-key"
    python demo_llm.py                 # Run all scenarios
    python demo_llm.py --simple        # Just the quick demo
    python demo_llm.py --advanced      # Advanced scenarios only
    python demo_llm.py --delegation    # Multi-agent delegation scenario
    python demo_llm.py --dlp           # Data Loss Prevention scenario
    python demo_llm.py --no-pause      # Run without pausing (good for CI)
    python demo_llm.py --anthropic     # Use Claude instead of GPT

Note: This will make real API calls and cost a few cents.
