Changes

base_reverse_dns_types.txt removed; sortlists.py now reads the authoritative type list directly from parsedmarc/resources/maps/README.md. The README's industry list (between new  /  HTML-comment markers) is now the single source of truth, eliminating the drift risk between the data file and the documented list. Before validating the map, sortlists.py also normalizes the README block in place: trims whitespace, deduplicates case-insensitively (errors on case-conflicting entries), and sorts entries alphabetically — so adding a new type is just inserting a - New Type line anywhere inside the markers. Also fixes a pre-existing typo in the precedence rules where rule 4 said Web Hosting but the canonical type used in 4,176 map rows is Web Host.
Maintenance tooling no longer ships in the wheel/sdist. The Python scripts under parsedmarc/resources/maps/ (collect_domain_info.py, classify_unknown_domains.py, detect_psl_overrides.py, detect_rebrands.py, sortlists.py, plus the previously-already-excluded find_bad_utf8.py and find_unknown_base_reverse_dns.py) are maintainer-only batch tooling, not parsedmarc runtime code. They have always been in the repository for convenience but were unnecessarily included in distributions, pulling reviewer attention and contributing nothing to end-user functionality. The build now excludes any .py file under parsedmarc/resources/maps/ whose name doesn't start with an underscore via a single glob pattern (parsedmarc/resources/maps/[!_]*.py), so future maintainer scripts added to that directory are excluded automatically while __init__.py continues to ship. The directory's __init__.py and the runtime data files (base_reverse_dns_map.csv, known_unknown_base_reverse_dns.txt, psl_overrides.txt) continue to ship — they're loaded at runtime via importlib.resources.files(parsedmarc.resources.maps).
