) [hist] Chi2Test: Support residuals for 2D/3D histograms Fixed bug where Chi2Test only stored residuals for 1D histograms. For 2D/3D histograms, the residual array indexing ignored j and k loop indices, causing incorrect storage. Added resIndex counter for each comparison mode (UU, UW, WW) to properly index the residuals array for multi-dimensional histograms. Fixes root-project#20761 (cherry picked from commit 5b770f8)
