Change default to SDXL-Turbo and robot animal examples

Default model: SD-Turbo → SDXL-Turbo
- Better quality (⭐⭐⭐ vs ⭐⭐)
- Only 4s slower (17s vs 13s)
- More impressive demos
- Better showcases LLM enhancement

Demo theme: Robot animals
- "robot puppy", "robot kitten", "robot owl"
- SD handles these well (no logo/text issues)
- Adorable and engaging for demos
- Shows enhancement clearly (simple → cute + detailed)
