Technical summary

tox native TOML configuration can raise a Requirement error while parsing requires.

Normalize native TOML requires entries into packaging Requirement strings before validation.

This issue is specific to native TOML configuration, so legacy ini parsing should not be rewritten.

The snippet uses native project logic; native TOML dependency values are normalized before tox builds Requirement objects. 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 tox; print('smoke test OK')"
