No-Fly Zone (NFZ) and geofencing utilities

Provides geofencing functionality for FAA Part 107 compliance:

* No-fly zone polygon definitions

* Point-in-polygon checking

* Path/line segment intersection detection

This module implements AV-03 (Geofencing) control from the compliance catalog. Used by strategic-dtsop to reject flight plans intersecting NFZ polygons.

:::note
All coordinates use WGS84 coordinate system
