Feedback Analyzer Training Script

Trains the feedback analyzer agent to categorize and prioritize feedback.
Uses actual feedback data from MongoDB + synthetic training examples.

This is USEFUL training - helps you triage real feedback efficiently.

Usage:
    python train_analyzer.py --mode setup     # Setup and test
    python train_analyzer.py --mode train     # Run training iteration

Requirements:
    - OpenAI API key or local vLLM endpoint
    - MongoDB with feedback collection
    - Agent Lightning 0.2.2+
