Research direction
Start by reproducing StdioServerParameters initialization in a Windows 11 Jupyter Notebook with Python 3.11, then compare the subprocess.Popen path with the working IDLE and Quart cases. Investigate the fileno failure and identify the SDK entry point involved; done means the notebook case works without regressing the other environments and has regression coverage.
