- pyproject.toml: setuptools build, deps (requests), dev extra (pytest),
pytest config with opt-in `live` marker
- tests/: 95 offline tests locking every series-ID encoding against
known-good IDs (regression guard for the JOLTS/OES/ECI/productivity/QCEW
fixes), plus a live API smoke test behind `-m live`
- README: install-as-package + test instructions; drop the now-resolved
"no packaging"/"no tests" limitations
- gitignore build/test artifacts
