PIF + OpenAI Python SDK Integration Example

This example demonstrates how to route OpenAI API requests through
the Prompt Injection Firewall (PIF) proxy for real-time prompt
injection detection.

Prerequisites:
    pip install openai

Usage:
    1. Start PIF proxy:
       pif proxy --target https://api.openai.com --listen :8080

    2. Run this script:
       OPENAI_API_KEY=sk-... python openai_example.py
