build_archive.py had no lint or test coverage, which is how the obsolete
requirements/pyproject mirror check slipped through unnoticed. Close that gap:
- Add tests/test_build_archive.py: a network-free smoke test that runs the
manifest check, dependency parsing, tarball build, and re-verification, and
asserts the moved docs/ files, LICENSE, and package sources are packaged.
- Lint build_archive.py in both the local gate (scripts/check.sh) and the CI
workflow; fix the one issue this surfaced (unused variable py_bin).
- List the new test in the REQUIRED_FILES manifest.
