fix(physics): match live tangent response transitions

Correct the common projection to spin*0.4 + normal_velocity*response_tangent and seal line/circle behavior against current Wine one-substep traces. Preserve record-two's in-response special-respawn continuation, producing the live (16698,21191)/(-302,-1809) state after publishing (17000,23000)/(0,3040), and update the readable C evidence.

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
- rumdl check original/C_RECONSTRUCTION_FINAL_AUDIT.md tdkpin-rs/CHANGELOG.md tdkpin-rs/RECONSTRUCTION.md tdkpin-rs/README.md
- live Wine record 2 trace: /tmp/original-special-respawn.csv
- live Wine object 155 trace: /tmp/original-circle155-after.csv
- git diff --check
