feat: initial ComfyUI_UltimateSGUpscale
Recreates UltimateSDUpscale features using built-in ComfyUI nodes
(SplitImageToTileList, ImageMergeTileList) plus a small GenerateSeamMask
helper node.
- GenerateSeamMask: creates white-band mask at tile seam positions
- Workflow JSON: 22-node tiled upscale pipeline with:
- Pass 1: model upscale + tiled img2img redraw
- Pass 2: targeted seam fix using SetLatentNoiseMask
- Unit tests for seam mask generation
