Square wall corners hold grains, liquids and gas (t39)

Browse Source 
Powder, liquid and gas no longer step diagonally between two solid
cells; flyers and diagonal tube intakes obey the same corner. World
generation settles with the rule off, so seeds make the same worlds.

## Decisions
- **Square corners hold grains (t39, 2026-10-26).** The owner wants square wall staircases to
hold material instead of leaking through each touching corner. Powder, liquid and gas cannot
step diagonally between two solid neighbours; powder neighbours still allow free piles to
slide as before. Free flyers and diagonal screw intakes obey the same solid-corner boundary.
Screw lane transport is unchanged. World generation disables cell corner sealing while
settling loose ground, preserving existing seed layouts. This supersedes the square-wall
leakage described in the t36 decision below.
The newest are at the bottom. The dates are when the decision was made or built.
**Up to 2026-10-19** (early design, stated by the owner): everything in "What the owner wants"
