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.
