Getaway evidence props

Spawns the unrecognized white panel van at the motel forecourt (-34,82), checks interaction distance, and applies/removes the burned-coupe visual. Driver owns vehicle control, detection, mission transitions and police state. Every spawned prop is temporary and scoped to its owning player; callers pass their car into burn/stop so one player's retry cannot clear another player's effects.

The vehicle change and burning-car sequence adapt GTA VI Extended Look 16:08–16:43; see design/extended-look.md. The Van bundle is generated original PS1 demake artwork. Flame/smoke reuse the engine's measured combat explosion effect with reduced debris and lighting.
