Technical summary

PDM poetry.py author parsing can fail on valid Poetry author strings because the regex is too narrow.

Loosen the author parser to accept names with punctuation/spaces and optional email portions, then normalize the captured fields.

The relevant code path points at formats/poetry.py, so the parser should be fixed at Poetry metadata import time.

The snippet uses native project logic; author strings from project metadata are parsed before PDM serializes them into core metadata. 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')"
