fix(input): restore original nudge and tilt behavior

Replace the float nudge direction, cooldown, and decaying meter with the
scan-code-specific Win16 behavior. Left Shift and keypad 3 now use the original
random directional impulse, while Space uses the reconstructed random horizontal
and vertical formulas with scalar 15 and wrapping millipixel velocities.

Track the original 16-bit tilt counter: each nudge adds 25, compares against
30 + Random(10), and the selected detail timer decrements a nonzero counter once
per callback. Allow the same input while a ball waits in the launcher, retain
bonus state when tilt latches, clear flippers immediately, and keep Right Shift
only as a documented modern alias for keypad 3.

Test Plan:
- `cargo test --all-targets` -- passed, 57 tests
- `cargo clippy --all-targets -- -D warnings` -- passed
- `rumdl check tdkpin-rs/CHANGELOG.md tdkpin-rs/README.md tdkpin-rs/RECONSTRUCTION.md` -- passed
- `git diff --cached --check` -- passed

 ### Fixed
 
+- Replace the cooldown/float-meter nudge approximation with the original
+  Left-Shift, keypad-3, and Space formulas using scalar 15, the shared Borland
+  random stream, 32-bit velocity wrapping, and the decaying 16-bit `+25` tilt
+  counter with its randomized `30..39` threshold.
 - Replace the Xorshift gameplay RNG with the original Borland linear stream and
   unbiased `Random(n)` high-word mapping. Launcher variation, effect selection,
   claw terminals, and magnetic-field impulses now share the recovered sequence.
