Replace the overlap-and-separate circle approximation with the original swept ball-center entry test and radial/tangent fixed-point response. Preserve every type-1 record's Real48 rebound and tangent coefficients, plus the bumper normal kick derived from the 3800-unit speed scalar. Unify line and circle traversal in original object-id order and remove the old floating passive-circle and bumper impulses. Add exact tests for live object 155 and bumper 51 transitions, and keep moving flippers as the explicit remaining collision approximation. Test Plan: - `cargo test --all-targets` -- 44 passed - `cargo clippy --all-targets -- -D warnings` -- passed - `cargo build --profile production` -- passed - 20-second deterministic launch traversed bumpers and drained without rescue - live object 155 and bumper 51 fixed-point transitions matched exactly - `git diff --cached --check` -- passed
