Halftones 0.4.1

Spot-color smoothing — a global Smoothing slider that cleans up rough separations by jointly smoothing the color-ownership partition. Because every pixel always belongs to exactly one layer, adjacent layers never erode apart and leave paper showing through. Low values remove stray specks; higher values smooth jagged boundaries.
Image pre-processing (Transform panel) — Blur (smooth gradients / suppress source noise), Sharpen (unsharp mask with adjustable radius, so detail holds through the screen), and Noise (film grain to break up banding). All run before halftoning.
Background-layer bleed — extend a background color plate outward into the margin by an adjustable amount.

Channel PNGs now use the full print page — margin, crop marks, alignment marks, and a plate label, matching the PDF (previously bare image rasters).
Layer-number plate labels — spot plates are labelled One, Two, Three… (key plate "Key") instead of color names, fixing filename collisions when two colors share a name. Labels are staggered across the page so they don't overlap when plates are stacked, sized to fill the crop-mark waste strip, and nudged clear of the top-center alignment mark.
Dropped redundant threshold / flat-vs-halftone text from spot PDF labels.

Output readout now shows the full printed sheet size in inches (image + margin + crop-mark waste), not raw pixels.
Alignment marks loosened to sit comfortably within the waste strip (~0.1" clearance) instead of nearly touching the cut line.
Reorganized the Halftone and Output control panels into clearer groups.
Color Proof now exports background bleed correctly into the margin.
Blur/Sharpen fixed to actually take effect in the native app (the old canvas-filter path was a no-op in the Tauri webview).
