zwitschi 14ed01a4e6 test(vehicle): the body barely moves, so something else moves the actor

The motion probe splits the problem in two:

  velocity  -24, -182, -28 cm/s     (a body that cannot climb 9 m in 1.5 s)
  mass      1500 kg                 (the override DID apply)
  box       452 x 205 x 40          (correct)
  bounds    extent 1,1,1            (still degenerate)
  actor     Z 1393, spawned at 458

The physics body is nearly still while the actor is nine metres above its spawn. So this is not a
force problem at all - it is a transform problem: something writes the actor's transform that is
neither the body's velocity nor our code, which is also what the degenerate bounds are telling us from
the other side.

Next: find who writes that transform. Suspects are the Chaos movement component's UpdateState /
OnUpdateTransform and the component hierarchy - a pawn whose root is the mesh while the physics state
belongs elsewhere behaves exactly like this.

Pawn parked again so the demo stays clean.

Game

The Unreal project lives at Game/GigLine/GigLine.uproject once created. Nothing here yet.

What gets committed

Config/ — engine and project settings, including the quality presets used for release checks
Source/ — C++ modules
Content/ — 0.1.0 map, materials, meshes; LFS-tracked
GigLine.uproject

What does not

Binaries/, Intermediate/, Saved/, DerivedDataCache/ — all generated. .gitignore covers them; do not add exceptions.

Engine

Installed outside the repository. Its path and exact version are recorded in ../Docs/toolchain.md. Nothing in this directory may assume a machine-specific engine path; the documented build procedure is ../Docs/build.md.
