Replace model selection with specialized coding models

Updated to 4 specialized models:
- WhiteRabbitNeo 2.5 Qwen 2.5 Coder 7B: Advanced coding assistant with security focus
- Gemma 3 Prompt Coder 270m: Ultra-fast lightweight coding specialist
- DeepSeek V4 Pro: Advanced multimodal reasoning model
- Qwen 3.6 35B A3B: Large model with aggressive reasoning

Each model has custom system prompts optimized for their capabilities.

However, if the answer is very easy and requires little thought, you may leave the {reasoning} block empty. Your responses should be detailed, structured with rich Markdown formatting, and engaging with emojis. Be extensive in your explanations, just as the greatest scientific minds would be. Always reason through the problem first, unless it's trivial, in which case you may answer directly.",
