ddidderr db0ec0bdc4 fix(random): continue Borland seed across games
The original RandSeed is program-global and is initialized once at startup.
Rust stored the exact Borland generator inside Game but discarded its final
state at game over and seeded every following game from Macroquad again,
breaking stream continuity across high-score/attract flow.

Expose the current seed, retain it when the App consumes a finished game, and
construct the next game from that value. Attract, high-score, and portable UI
continue to consume no gameplay draws.

Test Plan:
- `cargo test --workspace --all-targets --all-features` -- 125 passed
- `cargo clippy --workspace --all-targets --all-features -- -D warnings` -- passed
- `rumdl check --flavor commonmark RECONSTRUCTION.md CHANGELOG.md` -- passed
- `git diff --cached --check` -- passed

ddidderr 1f0085902c fix(physics): port the Borland Real48 collision core
Add a bit-exact six-byte Real48 implementation for integer conversion,
rounding, comparison, add/subtract, multiply/divide, and Newton square root.
Use the normalized Borland random-register result and route speed clamps,
segment/circle detection, moving flippers, captures, triggers, and magnetic
fields through the recovered arithmetic instead of host floating formulas.

Preserve Real48 spin per ball and feed it through the original tangent/spin
response, separating zero-spin C fixtures from retained-spin Wine traces.
Replace path-progress selection with surface-distance ordering and implement
dynamic records 174/175, including impulse transfer to the other slot,
normal_velocity-1000 response, and the second post-collision speed clamp.

Test Plan:
- `cargo test --all-targets` -- passed, 69 tests
- `cargo clippy --all-targets -- -D warnings` -- passed
- `rumdl check tdkpin-rs/CHANGELOG.md tdkpin-rs/RECONSTRUCTION.md` -- passed

ddidderr c25287186a fix(game): use the original Borland random stream
Replace the Xorshift state with the reconstructed Borland Win16 generator,
including its wrapping linear update and high-word Random(n) mapping. Route
launcher clamp variation, effect selection, and claw terminal choices through
one shared stream so seeded event order follows the executable.

Use the same stream for the recovered magnetic-field response. Fields now scale
horizontal speed by 0.9 and choose the upward impulse from
-3800 * (1 - Random * 0.3) instead of assigning a fixed -3000 velocity. Adjust
deterministic scenario expectations where the original stream permits a second
natural claw capture or does not force one during a particular autoplay seed.

Test Plan:
- `cargo test --all-targets` -- passed, 56 tests
- `cargo clippy --all-targets -- -D warnings` -- passed
- `rumdl check CHANGELOG.md RECONSTRUCTION.md` -- passed
- `git diff --cached --check` -- passed
