fix(attract): restore all remainder-driven cycles

The same raw Div32 pattern used by the item animation appears in every nested
idle phase: after division by 32, 40, or 16, the binary copies the remainder
from CX:BX before the second division. Readable C and Rust used quotients for
targets, word quads, the record strip, and the four-point chase, turning short
repeating chases into slow one-shot progressions.

Use `%32/2`, `%32/4`, `%40/4`, and `%16/4` for those cycles alongside the
already corrected `%144/8` items. Preserve the first-cycle phase-zero delay,
then repeat each incremental overlay state exactly. Add C and Rust coverage at
phase activation, reversal, deactivation, and wrap boundaries.

Test Plan:
- raw instruction review at `1000:01b7-063b` -- all remainder transfers confirmed
- `cargo test --workspace --all-targets --all-features` -- 125 passed
- `cargo clippy --workspace --all-targets --all-features -- -D warnings` -- passed
- `bash original/tools/test_reconstructed_c.sh` -- passed
- `python3 original/tools/audit_reconstruction.py --require-complete` -- passed with zero incomplete or unclassified units
- `cargo run -- --simulate attract --step 145 --screenshot /tmp/tdkpin-attract-remainder.png` -- passed; visually inspected at 640x460
- `rumdl check --flavor commonmark RECONSTRUCTION.md CHANGELOG.md` -- passed
- `git diff --cached --check` -- passed
