fix(rules): scope double scoring to the active ball

Browse Source 
The binary stores the diamond-bank double flag at receiver +0x0bdc and clears
it in normal_ball_end. Rust stored that flag on Player, so it incorrectly
survived every normal drain and player turn. The special effect-seven respawn
is intentionally different because it bypasses normal_ball_end.

Represent the flag as an explicit ball-double state on Game. Clear it only on
the normal ball-end path, preserve it through the special respawn, and make the
first completed diamond bank after a normal drain re-enable double scoring
without adding 100,000 secondary points. Keep the independent multiball factor,
so both active factors still stack to 4x.

Test Plan:
- `cargo test --workspace --all-targets --all-features` -- 117 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

- Advance media/extra-ball thresholds only from score additions, preserve
32-bit score wrapping, and restore the ninth-diamond ordering: its 24,464
award remains single, then permanent double scoring and all three magnetic
fields activate before the collision's static score. Every later completed
bank adds 100,000 to the secondary score. Marker comparisons retain the
binary's signed-high/unsigned-low 32-bit ordering after score wrap.
