Playable table (hinge-motor flippers, plunger, bumper, drain) plus a headless
probe harness that measured, per engine: tunneling of a fast ball through a
1 cm wall with CCD off/on, and hinge-motor drive. Findings in godot/README.md:
Box3D never tunnels even with CCD off, but its hinge motor sign is inverted
vs Jolt/GodotPhysics, and Jolt blows through angular limits that Box3D holds.
Ships a from-source macOS arm64 libgodot-box3d.dylib (upstream has no
releases). Also gitignore the remaining Microsoft media at repo root.
