Extend tile extraction by one pixel so adjacent tiles share boundary vertices. Previously each tile covered [r0, r0+tile_size) exclusively, leaving a one-pixel gap where no geometry existed, producing visible seam lines in shaded terrain.

Summary
terrain[r0:r0+tile_size]), leaving a one-pixel gap between adjacent tiles where no geometry existed. This gap showed up as visible seam lines in the shading.r0+tile_size+1) so adjacent tiles share their boundary row/column. The shared vertices make the surface continuous.Test plan
