Technical summary

PDM resolution through unearth can abort on an invalid requires-python value such as >=3.4.*.

Catch InvalidSpecifier/InvalidRequirement from unearth link evaluation, skip that link, and continue evaluating other candidates.

This issue is about skipping a bad link, so invalid metadata from one package should not terminate the whole resolver run.

The snippet uses native project logic; the candidate requires-python value is normalized before PDM compares it with the project interpreter range. 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 pdm; print('smoke test OK')"
