Two robustness fixes for near-identical seamless grids (e.g. a 2x2 of very similar panels):
- gutter detection now requires near-solid bands (std<0.01), so a dark content strip at a seam is no longer mistaken for a gutter (which caused a 2x2 to split into 2)
- seamless mode keeps only seams within rel_frac of the strongest, dropping content edges that used to cause over-splitting

Detects how a stitched image is divided and splits it into panels. No model, CPU, any resolution. Handles regular grids, uneven grids, irregular (bento) collages, and seamless grids.
