v0.19.0 — map chart type
New: map chart type 🗺️
Geographic concept maps — score/tag countries & US states (choropleth + categorical), drop points of interest, and connect them with routes and edges. Auto-fit projection by extent; gazetteer-backed (GeoNames) + ISO 3166 name resolution; on-map labels with collision escalation; gazetteer/region autocomplete APIs (completeMapPlaces / completeMapRegions).
Pipeline: parse → resolve → layout → render (src/map/), d3-geo renderer, lazy-loaded geo data assets. Renders via render() + the CLI. See language reference §25 / spec §24B.
Also: dropped 2 platform-fragile raci/mindmap compressed-scaling snapshots (kept the fonts >= 9px invariant).
