Waypoint ETA

AeroSpace • Haversine legs • cumulative hours

Waypoints with lat/lon (and optional sequence). Sort if out of order, then compute ETA in hours from start to each waypoint using constant ground speed — distance/speed only when timestamps are missing.

① Sort by seq if present

② Leg time = haversine_km / speed_kmh

③ Cumulative sum → ETA list
