Stickiness gated every diagonal step, so clay lumps, snow, wood chunks,
ash and dirt crawled down sloped walls (a clay grain never got down a
20-piece slope). It now applies only grain against grain: a grain
resting on anything built always tries its diagonal step, so chutes
carry every material while heaps keep their shape. The random draw is
unchanged, so generated worlds stay the same.

- New Sloped wall piece: a half-block triangle in any wall material, at half a wall's cost.
Dragging walls or slopes at about 45° lays a diagonal line; the drag picks the slope's
orientation and T flips or turns it.
- Each slope fills one cell past its corner, so a diagonal run is sealed against grains and water.
- New test/t_slopes.js: a slope funnel passes 400/400 sand (square steps 379/400).
