"""Smoke test for the archive builder (build_archive.py).

Guards the packaging manifest and dependency parsing so regressions -- a moved
or renamed file, a broken REQUIRED_FILES entry, or the requirements/pyproject
dependency handling -- fail here in the normal test run instead of only
surfacing at release time. Runs the pure build steps (no network, no pip).
