Compare SAFETY OVERRIDE dispatcher vs CLEAN dispatcher.

This experiment helps identify:
1. Which queries truly NEED keyword fallback
2. If LLM intelligence degradation is caused by:
   - Model choice (gemini-3-pro-high vs gemini-2.0-flash-exp)
   - Over-guiding system prompts
   - Context pollution
   - Poor tool descriptions
