Interactive Semantic Router Demo

This script provides an interactive demo of the semantic router capabilities:
- Single classification test (cache demo)
- All classifications test (10 golden prompts)
- Reasoning showcase (CoT vs standard routing)
- PII detection test
- Jailbreak detection test

URLs are dynamically discovered from OpenShift routes (requires oc login).
