- Add DeepSeek provider routing: deepseek-chat/deepseek-reasoner use
api.deepseek.com, other models use SiliconFlow
- Add stream_with_reasoning() using raw OpenAI SDK to capture
reasoning_content (langchain_openai strips this field)
- RAG chain and conversation chain both use stream_with_reasoning
for proper reasoning display in thinking models
- Frontend model selector: grouped by provider (DeepSeek official +
SiliconFlow), default changed to deepseek-chat
- Regenerate message converted to streaming with reasoning capture
- Minor UI: globals.css additions, chat store refactoring
