feat(editor): add --gen-texture-honeycomb hexagonal-cell pattern

Browse source 
42nd procedural texture: hexagonal cell tiling produced by
Voronoi over a triangular seed lattice — alternating-row hex
seeds at horizontal step sqrt(3)*s and vertical step 1.5*s
naturally produce perfect hexagonal Voronoi cells without
needing the full pointy-top hex-tile math.

Border pixels are detected by ratio of second-nearest /
nearest seed distances (1.04x threshold) so border thickness
scales naturally with hex size and stays a couple of pixels
across the whole image. Useful for beehives, dragon scales,
sci-fi panels, magical wards, mosaic tile floors. Defaults
to 16-px hex side.
