Subject: [PATCH] deps: add langchain-deepseek for native DeepSeek support

Adds official LangChain DeepSeek integration to replace ChatOpenAI
wrapper approach for DeepSeek models. Native integration provides:
- Better tool_calls argument parsing
- DeepSeek-specific error handling
- No OpenAI compatibility layer issues

Version 0.1.20+ includes tool calling support for deepseek-chat.
