New ColorMatchingNode (Color Matching Ops): image + reference inputs, one
output. Methods LAB/RGB/Histogram (LAB default) and a target selector
(All/Lightness/Color) that keeps only the matched Oklab lightness or color.
Statistics-only, so inputs may be any size. Live in-node preview.
Filter Ops: add Laplacian Sharpen (4-/8-neighbor kernel) and Unsharp Masking
(Gaussian amount/radius/threshold), with matching JS live previews, widget
visibility, and tooltips.
Layer Blending: rename to Layer Blending Ops, drop the unused preview_ref
output, and make the live preview match the backend exactly (resize fg to bg
size, default opacity 255, per-mode clamp parity) - fixes big mismatches e.g.
Linear Dodge (Add) at high opacity.
Rename Color Matching node display to Color Matching Ops. Raise color-match
preview resolution to 1024 to tighten preview-vs-output stats.
Previews: use widget.last_y to stop the preview box overlapping the last
widget (all nodes, incl. Channel Ops); hide the preview box until a preview
exists; auto-size the node to a sensible preview area on first preview; keep
fresh Filter Ops compact instead of huge with empty space.
README: add per-node preview GIFs (channel_ops/Layer_blend/filter_ops/
color_match) and document the new node/effects; drop the old preview.gif
reference.
