Build failed due to python setuptools version.

[trairia]

pkg_resources module has obsolete on python-setuptools 82.0.0.
So nanopb_generator.py fails generate code.

My build environment are following.

• commit: 89d446e
• Build Platform: Windows 11
• CMake: 4.2.3
• Python: 3.14.2
• nodejs: v24.13.0

I think it need to specify setuptools version in requirements.txt.
Or need upgrade nanopb source to ver 0.4.9 or later
