Server was sending visible_tiles without tile type data, so the client
could not distinguish floor from wall in live mode. Add TileKind enum
(Floor/Wall/Door/Object) to VisibleTile, populated from WalkabilityMap
in the NaturalVision perception query. Update test fixtures to include
the new field. Uses #[serde(default)] for backward compatibility.

Extract visibility geometry into a separate system behind a
PerceptionQuery trait, enabling D-017 perception mode swapping.
Two-stage pipeline: compute_visibility_geometry writes to
VisibilityGeometry resource, compute_observer_snapshot reads it.
Remove KnowledgeGraph from compute_nearby_interactions (simulation
phase boundary violation). Verb availability stays in simulation;
POI-based priority adjustment moves to observer via
apply_poi_verb_priority helper.
