Kelsi 85e02a6132 feat(editor): add --gen-mesh-mine-cart underground transport ...

73rd procedural mesh primitive. Open-top mining cart on
4 wheel boxes:

  • bin: 5-piece basin construction (bottom slab + 4
    perimeter walls), same arrangement as
    --gen-mesh-water-trough
  • wheels: 4 cube boxes at the corners, inset by
    wheelInset and sitting on the ground (y from 0 to
    2*wheelR)
  • bin sits on top of the wheels at y = 2*wheelR

All axis-aligned — exercises every shared helper. Useful
for mines, dwarven forges, gnomish junk-yards, abandoned-
tunnel set dressing, salvage scenes.

Default 0.9 × 0.5 m bin with 0.08-radius wheels gives the
classic narrow-gauge ore-cart silhouette. The 4-wall basin
construction (verified via --info-mesh-stats: 6 non-manifold
edges at the wall corners — same as --gen-mesh-water-trough's
expected branchy edges) means the cart can hold collision-
visible ore inside if a content author drops in another
primitive.
