fix(physics): restore swapped-component tangent driver

Browse Source 
Use the binary tangent velocity -(vx*normal_y + vy*normal_x)/length, then combine it with retained spin and the Real48 response coefficient. This single formula matches live outer/inner shooter walls, object 155, bumper 51, and the horizontal special-drain response; update C evidence and keep autoplay coverage on a target-reaching seed.

Test Plan:
- bash original/tools/test_reconstructed_c.sh
- python3 original/tools/audit_reconstruction.py --require-complete
- cargo test --all-targets
- cargo clippy --all-targets --all-features -- -D warnings
- original Wine traces: /tmp/original-outer-wall.csv /tmp/original-inner-wall.csv /tmp/original-circle155-after.csv /tmp/original-special-respawn.csv
- git diff --check
