Buried wreck: PARK the collision volume (count-zero alone doesn't unblock)

Browse Source 
The mech-vs-mech gather (Mover::GetCurrentCollisions) tests
mover->collisionVolume DIRECTLY -- it never consults collisionVolumeCount --
so the previous inert fix left the stale box blocking at the wreck spot.
The count-zero now serves only to stop MoveCollisionVolume from re-placing
the box, and the box itself is parked 100km underground where it intersects
nothing.  Verified: the autodrive harness, previously pinned at ~7m from the
enemy, drives straight through the spot after burial (341,155 -> 992,-971).
