- 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

Implement per-entity KnowledgeGraph component with BTreeMap storage
for deterministic iteration (D-010). StableEntityId + EntityRegistry
for entity identity across save/load. KnowledgeEventQueue + processing
system for decoupled knowledge updates. Decay system runs once per
game-minute. All types conform to D-041 canonical structs.
