Technical summary

Conan python_requires package_id behavior cannot be controlled through the expected package_id_python_mode configuration/attribute.

Read package_id_python_mode from the conanfile/configuration and apply that mode when python_requires contributes to package_id.

The relevant code path includes issue 15774 and python_requires, so the patch should target package ID computation rather than package loading.

The snippet uses native project logic; the package ID mode is computed from the conanfile and configured default before Conan records the python_requires mode. The helper result is consumed directly by the patched code path.

After applying the patch, keep the import smoke test for the affected package:

python3 -c "import conan; print('smoke test OK')"
