"""Patch frontend ChatInput.tsx: Replace entire DEFAULT_MODEL_OPTIONS array.

OpenRouter model routing on backend:
- Models with openai/google/, openai/deepseek/, openai/nvidia/, openai/poolside/ → OpenRouter
- Models starting with openai/openrouter/ → OpenRouter  
- All others → HF Inference Router

Owl Alpha removed (provider Stealth broken on OpenRouter).
Replaced with Gemma 4 9B (free, reliable on OpenRouter).
