instead of for (_, v) pattern).

- Use #[derive(Default)] + #[default] instead of manual Default impls
for FacingDirection, KnowledgeState, RelationshipState, EntityVisibility
- Replace manual modulo check with .is_multiple_of()
- Collapse nested if in shadowcast symmetry check

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.
