feat(editor): add --gen-texture-argyle sweater-knit pattern

Browse source 
31st procedural texture: classic argyle pattern done by working
in a 45-rotated coord system (u, v) = (x+y, x-y) so lozenges
become axis-aligned squares for the checkerboard step. Diagonal
stitch lines fall out of u%cell and v%cell crossing zero.

Three-color: A/B for the alternating diamond fill, third color
for the diagonal stitch overlay. Defaults to 64-pixel cells with
2-pixel stitches. Useful for sweater fabric, seat cushions,
heraldic banner overlays.
