Spatial chain for Sprint 23 (#576, #577, #578):
- TileKind enum (Floor/Wall/Void/Restricted) on WalkabilityMap with
set_tile_kind/tile_kind API, backward-compatible with existing
is_walkable/set_walkable
- Location YAML tile format: tiles as string arrays (F/W/V/R chars),
load_location_tiles() stamps tile data onto WalkabilityMap from
ContentStore on production startup
- Chunk streaming system: ChunkLoadRadius + ChunkStreamingCadence
resources, loads/unloads chunks around player position on cadence.
v0.1 radius covers full district (no streaming stutter)
