PyPI package metadata + maintenance API

Normalize PyPI's sprawling JSON for a package into one clean schema — latest version, resolved license (from metadata or classifiers), runtime dependency list (extras excluded), supported Python versions, release count, age, days-since-last-release, yanked flags, and a maintenance read (active/stale/abandoned/yanked). Parallels dev-npm-package for Python. Answers 'metadata for this PyPI package', 'what license does requests use', 'is this Python package maintained', 'dependencies of this pip package', 'is this release yanked'.
