Pre-push surfaced fmt + clippy (-D warnings) failures in the new code:
- rustfmt the 6 new/changed atlas files + the bench example.
- features.rs: HashMap → BTreeMap (project bans HashMap for determinism via
clippy disallowed_types; the bucket map is lookup-only either way).
- attractor_matching.rs: drop now-redundant .clone() on AttractorType (it
became Copy in #953) — clippy clone_on_copy.
- drainage.rs tests: manual range → (1..=12).contains(&n).
- features.rs test: drop .clone() on Copy AttractorType.

examples/bench_layer1 times run_layer1 on a synthetic 512x256 heightmap
with a phase breakdown (drainage / terrain analysis / feature extraction).
Post-optimization: ~106ms/body total (drainage ~45ms). Documents the
synthetic-terrain caveat (real heightmaps via #963).
