Graham McIntire 5a97776fd5 feat(buildings): MS Global ML Building Footprints quadkey + tile fetcher ... Phase 1 of building-blockage support: implements quadkey math (Bing/MS tile encoding), looks up the MS dataset-links index for UnitedStates, and downloads csv.gz quadkey tiles to /data/buildings (overridable via :buildings_cache_dir). Index is cached 24h; tiles are written once and reused. No path-analysis wiring yet — that's the next slice.		2026-04-26 10:33:25 -05:00
