YueGuobin b936a52f6f docs: add LangGraph Agent and tool output serialization documentation ...

Added new section in ai-chat-api-design.md explaining:

- LangGraph Agent architecture and main components
- tool_node function and tool output serialization mechanism
- Why serialization happens in tool_node (not agent_service)
- Tool output data flow diagram showing SSE and history paths
- Explanation of JSON format consistency across streaming and storage

This documentation clarifies the fix for single-quotes issue in
conversation history and helps future maintenance.
