Municipals: nest 1,823 city officeholders under their real counties

Pull Atlas's place→county crosswalk (Census TIGER 2024 places × county geometries, 32,041 places) into the build as a committed raw input, and use it to resolve municipal officeholders whose county was unknown. - data/place_county_crosswalk.jsonl — new raw input (place_geoid → county_geoid) - build.py — place-name+state → county_geoid → ACS county slug as a fallback in county_slug(); city_slug() generalized to non-FL bare place labels - data/sources/sources.yaml — provenance entry for the crosswalk _unresolved municipals: 1919 → 58. The remainder are genuine: CT planning regions (post-county), county-level rows mislabeled municipal upstream, consolidated city-counties (null label), Wikidata-QID placeholder names, and ambiguous same-name places — left unresolved rather than guessed. Join key is county_geoid (5-digit FIPS); the directory slug is taken from the ACS county node so municipals nest under the exact existing county dir. Deterministic (byte-identical rebuild); validate.py passes 19,721 records. Co-Authored-By: Claude Opus 4.8 <noreply@anthropic.com>
