Kitchen Wall Autotiling, Congestion Passing Lanes

The kitchen/counter wall run switched from individual flat-colored boxes to a real procedural autotile — seamless stone/brick texture, correct corner pieces, no visible gaps or seams at any join, and a safety cap on wall-run width so a very long run can't overflow its texture. Agents sharing a single grid cell (the congestion/passing mechanic later documented as Occupancy's 2-lane sharing) now visibly nudge to opposite sides of the tile and pass each other instead of overlapping. South-facing chair sprites had a flip/rotation fix (a south-facing chair was rendering mirrored or misrotated relative to the other three facings).
