pyright --createstub seems to not do anything? #11043
Description
Describe the bug
I've tried using pyright --createstub but it doesn't seem to be generating anything.
Repro steps:
mkdir repro
cd repro
npm install pyright
python3.14 -m venv .venv
.venv\Scripts\Activate.ps1
pip install pypdfium2
.\node_modules\.bin\pyright --createstub pypdfium2 --verbose
The output is the following:
No include entries specified; assuming c:\Users\Jakub\work\repro
Auto-excluding **/node_modules
Auto-excluding **/__pycache__
Auto-excluding **/.*
Assuming Python version 3.14.0.final.0

I then checked whether there's anything new in the current directory, but there wasn't. I tried explicitly making the typings directory (which, as far as I understand, is the output directory, assuming the default stubsPath) but that didn't change anything. When running without --verbose, there's not a single line of console output.

There's no code needed, here's the output of pip freeze though:
