docs: update v0.4.1 changelog (IF_TRADE fix only)

Reverted ChatDeepSeek integration approach as it conflicts with
OpenRouter unified gateway architecture.

The system uses OPENAI_API_BASE (OpenRouter) with a single
OPENAI_API_KEY for all AI providers, not direct provider connections.

v0.4.1 now only includes the IF_TRADE initialization fix.

 ### Fixed
-- Resolved Pydantic validation errors when using DeepSeek Chat v3.1 through systematic debugging
-- Root cause: Initial implementation incorrectly converted tool_calls arguments from strings to dictionaries, causing LangChain's `parse_tool_call()` to fail and create invalid_tool_calls with wrong format
-- Solution: Removed unnecessary conversion logic - DeepSeek already returns arguments in correct format (JSON strings)
-- `ToolCallArgsParsingWrapper` now acts as a simple passthrough proxy (kept for backward compatibility)
+- Fixed "No trading" message always displaying despite trading activity by initializing `IF_TRADE` to `True` (trades expected by default)
+- Root cause: `IF_TRADE` was initialized to `False` in runtime config but never updated when trades executed
+
+### Note
+- ChatDeepSeek integration was reverted as it conflicts with OpenRouter unified gateway architecture
+- System uses `OPENAI_API_BASE` (OpenRouter) with single `OPENAI_API_KEY` for all providers
+- Sporadic DeepSeek validation errors appear to be transient and do not require code changes
