Technical summary

Repository authentication repeatedly asks keyring for the same credentials during one PDM operation.

Cache the resolved repository credentials per source URL/name and reuse that value while the repository session is active.

This issue is specifically about repository auth and keyring caching, so the fix belongs in the auth lookup path rather than in dependency resolution.

The patched code wraps PDM's keyring lookup with a local cache where PDM builds repository authentication, including repeated missing-keyring results.

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

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