- Refactored `FiniteDifference1D` in `biology/diffusion.rs` to use safe `windows(3)` and `zip` iterators instead of `unsafe` manual indexing.
- Refactored `TuringSystem::step` in `biology/morphogenesis.rs` to use safe `zip` iterators for fused multiply-add operations, removing `unsafe` blocks.
- Replaced `unwrap()` with `expect("...")` in `simple_randomization` in `applied/clinical_trials/design.rs` to provide safer error messages for deprecated code.
- Verified changes with `cargo test`.
