Strip environment markers from detected uv dependency pins (#938)

## Summary
- strip PEP 508 environment markers before extracting uv versions from
dependency entries
- cover dependency-group pins with and without whitespace before the
marker
- cover requirements-style pins with markers

Fixes #920

## Validation
- npm ci --ignore-scripts
- npm run all
