Subject: [PATCH] fix: disable thinking chain for Xiaomi MiMo models

- Add isMiMoModel() method to detect Xiaomi MiMo models
- Add thinking: { type: 'disabled' } to request body for MiMo models
- Fixes issue #127 where reasoning_content was displayed instead of final result
- Does not affect other models (DeepSeek, OpenAI, Claude, Gemini)
