OVC v3.0.0

Local-Data-Only Architecture
OVC no longer downloads data from OpenStreetMap. All OSM/Overpass/osmnx dependencies have been removed. You provide your local files (Shapefile, GeoJSON, GeoPackage) — OVC runs the checks. No internet required, no API rate limits, no freezes.

What's New
Road QC Suite (3 checks)

Dangle Detection — finds unconnected road endpoints
Disconnected Segment Detection — finds roads completely isolated from the network
Self-Intersection Detection — finds roads that cross themselves
Geometry Quality Checks

Duplicate geometry detection
Invalid geometry detection (self-intersections, topology errors)
Area reasonableness (too small / too large buildings)
Compactness score (Polsby-Popper shape regularity)
Road setback violations
CLI Enhancements

--road-qc-only flag for standalone road QC without building data
--buildings](vscode-file://vscode-app/c:/Users/goldi/AppData/Local/Programs/Microsoft%20VS%20Code/6534f6ba76/resources/app/out/vs/code/electron-browser/workbench/workbench.html) is now optional when using --road-qc-only
