ci: fmt under stable 1.96 to make rust-ci green (follow-up) (#42)

## Summary

Follow-up to the merged CI-green PR. With rust-ci now running, `cargo
fmt --all -- --check` fails on `main` under the CI toolchain (stable
rustfmt 1.96) — the toolchain-pin landed before the formatting fix. This
brings the Rust sources to rustfmt-clean so rust-ci goes green.

## Changes

- **Rust hygiene:** `cargo fmt` (`src/codegen/affine_gen.rs`,
`src/codegen/wasm_gen.rs`) so `cargo fmt --all -- --check` passes under
stable 1.96.

## RSR Quality Checklist

### Required
- [x] Tests pass (`cargo test --locked --all-targets`)
- [x] Code is formatted (`cargo fmt --all -- --check`)
- [x] Linter is clean (`cargo clippy --locked --all-targets -- -D
warnings`)
- [x] No banned language patterns
- [x] SPDX license headers present on modified files
- [x] No secrets, credentials, or `.env` files included

## Testing

Verified locally with the CI toolchain (rustc/clippy/rustfmt 1.96.0):
`cargo fmt --check`, `clippy -D warnings`, `cargo check --locked`,
`cargo test --locked` all pass.
