fix: header property footgun, dead conftest, async test gaps, __version__

- Replace _headers @Property with _make_headers() method to avoid false dynamic impression
- Update client.py and async_client.py to call _make_headers() at construction
- Delete dead tests/conftest.py (fixtures shadowed in every test file, helpers unused)
- Strengthen async domain_overlap test to assert comma-joined value, not just key presence
- Add missing async link_intersect two-params test to match sync coverage
- Add __version__ = "0.1.0" to rankparse/__init__.py and __all__
