In windows poetry should return exit code Uint32 (permit over 255)

Feature Request

In Windows, many installer or packaging deployment system (like Microsoft SCCM) relies on exit code which is over255.

Reference

• https://docs.microsoft.com/en-us/mem/configmgr/tenant-attach/app-install-error-reference

Different Behavior between python app.py and poetry run python app.py

• python returns exit code as it is to os.
• poetry run python returns exit code limit to max 255.

How to reproduce

I made helloExit.exe which returns exit code 6501 .
and getExitCode.py like below.

import subprocess

completedProc = subprocess.run('./helloExit.exe')

# Print the exit code.
print("Exit Code: " + str( completedProc.returncode))

exit (completedProc.returncode)

Test Result

$ python getExitCode.py
Do some work
Do some cleanup
Exit Code: 6501

$ echo %ERRORLEVEL%
6501

$ poetry run python getExitCode.py
Do some work
Do some cleanup
Exit Code: 6501

$ echo %ERRORLEVEL%
255

WorkAround

Obviously, poetry should return exit code compatible with os (windows).
But, for a while, if someone need get exit code over 255, I guess they could follow below steps.

• let poetry make every package dependency.
• make venv in project using poetry config --local virtualenvs.in-project true
• activate venv with shell command ( .venv\Scripts\activate.* )
• use python start_app.py

Start by reproducing the behavior with the provided helloExit.exe and getExitCode.py examples, comparing direct Python execution with poetry run. Trace the poetry run entry point that forwards subprocess exit codes and verify that the Windows result preserves 6501 rather than limiting it to 255.
