Manual clippy-1.93 fixes that the prior machine-applicable sweep couldn't auto-
apply, all in cfg(test) modules and tests/ targets (invisible to the lib-only
pre-push clippy, hence accumulated unflagged):
- disallowed_types HashSet/HashMap → BTreeSet/BTreeMap (determinism rule):
shadowcast_bench.rs (×8, (i32,i32) keys), mood.rs, sound.rs. SoundEventKind
gains a PartialOrd/Ord derive (fieldless Copy enum) so it is BTree-usable.
- field_reassign_with_default → struct-init: disclosure.rs, monologue.rs (×2),
save_io.rs (keeps `mut` for the deliberate last-write-wins overwrite).
- assertions_on_constants on the EAVESDROP_THRESHOLD invariant → compile-time
`const _: () = assert!(...)`: listening.rs, cross_room_transitions.rs. This is
stronger than the runtime assert and needs no #[allow].
- approx_constant: settings/types.rs round-trip literal 3.14 → 2.5 (the value is
arbitrary test data, never meant to be PI — change avoids both the lint and a
suppression).
- drop_non_drop: vision.rs early Mut<WalkabilityMap> release → scoped block.
- unnecessary_get_then_check → contains_key: information_boundaries.rs (×3).
- cloned_ref_to_slice_refs → std::slice::from_ref: triangle_validation.rs.
- unused_must_use: input.rs dropped the unused .id() on a spawn.
cargo clippy --all-targets -- -D warnings is clean; cargo test green.

Formatting pass across simulation, perception, knowledge, NPC, and
test modules. Includes two clippy fixes in monologue.rs (.values()
instead of for (_, v) pattern).

Add Albert Ford's symmetric shadowcasting algorithm using rational
fraction slopes. Benchmarked 1.2-10.5x faster than recursive with
guaranteed symmetry (if A sees B, B sees A). Resolves Q-018 as D-035.
