ddidderr 64d41eb605 fix(game): preserve rule state across player turns
The rewrite reset wheel holes, top targets, collision latches, active records,
selected effects, and multiball readiness on every drain. The reconstructed
turn-state code instead saves all 175 live record states for the outgoing player
and restores the incoming player's mirror.

Add a per-player rule snapshot and save/load it at normal turn transitions.
Keep transient ball, claw, tilt, and presentation state global while retaining
each player's mechanism progress and contact/activation state across later
turns and extra balls.

Test Plan:
- `cargo test --all-targets` -- passed, 58 tests
- `cargo clippy --all-targets -- -D warnings` -- passed
- `rumdl check tdkpin-rs/CHANGELOG.md tdkpin-rs/RECONSTRUCTION.md` -- passed
- `git diff --cached --check` -- passed

[Unreleased]

Fixed

  • Preserve each player's complete rule-record state across turn changes instead of globally clearing wheel holes, top targets, 176 active/contact slots, selected effect, and multiball readiness on every drain.
  • Store lock-hole and effect awards in the original per-player secondary score instead of a global bonus. The fifth hole now transfers 310000 * score_multiplier, clears it, increments the multiplier and ball count, while effect 6 transfers the same display value and drain leaves it intact.
  • 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.
  • Restore the magnetic-field response as vx * 0.9 and a randomized -3800 * (1 - Random * 0.3) vertical impulse instead of a fixed upward speed.
  • Dispatch the original per-call-site sound sequences instead of assigning one guessed WAV to each logical event. This removes the nonexistent WAV 2022 playback and restores bank, trigger, capture, nudge, tilt, and drain cues.
  • Advance media/extra-ball thresholds only from score additions, preserve 32-bit score wrapping, and restore the ninth-diamond 24,464-point award plus the later double-score and secondary-score bank states.
  • Match the original 640x460 window, native 16x28 score glyphs, and TDK Pinball Machine 1.00 title so the recovered artwork is presented one-for-one instead of enlarged or resampled.
