Added detailed logging to patched_create_chat_result to investigate why
invalid_tool_calls.args conversion is not working. This will show:
- Response structure and keys
- Whether invalid_tool_calls exists
- Type and value of args before/after conversion
- Whether conversion is actually executing
This is Phase 1 (Root Cause Investigation) of systematic debugging.

Extended ToolCallArgsParsingWrapper to handle both tool_calls and
invalid_tool_calls args formatting inconsistencies from DeepSeek:
- tool_calls.args: string -> dict (for successful calls)
- invalid_tool_calls.args: dict -> string (for failed calls)
The wrapper now normalizes both types before AIMessage construction,
preventing Pydantic validation errors in both success and error cases.

Added ToolCallArgsParsingWrapper to handle AI providers (like DeepSeek)
that return tool_calls.args as JSON strings instead of dictionaries.
The wrapper monkey-patches ChatOpenAI's _create_chat_result method to
parse string arguments before AIMessage construction, preventing
Pydantic validation errors.
