Subject: [PATCH] feat: add DeepSeek v3.1 support with automatic thinking mode

- Add intelligent detection for DeepSeek v3.1 models
- Automatically enable thinking mode for v3.1 models
- Support flexible model naming patterns (v3.1, v3-1, deepseek-v3-1-250821)
- Maintain full backward compatibility with existing R1 models
- No breaking changes to existing configuration system

Users can configure DeepSeek v3.1 models via the configuration interface
without any code changes required.
