Native grind assist

The live acquisition and airborne board-adjustment path is now connected. See difficulty and integration details and grind families.

Core trajectory leaves82D6A398/82D6A168/82D6A840 are supplied with the real spline collection and indexed collision investigation. Accepted targets pass through selector scoring and KnownAir into GrindAirAdjust82D712E0. Difficulty uses the stock physics_mode80 field, not a new snapping radius.
