NegPy 0.22.0

0.22.0

• Tool-aware cursor: mouse pointer changes shape to reflect the active tool — pointing hand for WB Pick, crosshair for Manual Crop, open/closed hand for Move Crop, hidden cursor (brush circle) for Heal.
• Added IR Dust Removal: uses the infrared channel from IR-capable scanners (Nikon Coolscan, Epson flatbeds with SilverFast iSRD, VueScan 4-channel output) to detect and inpaint dust and scratches with near-zero false positives. Toggle and threshold slider in the Retouch panel — controls are disabled automatically when no IR channel is present in the loaded file.
• IR channel is read from: 4-channel TIFFs with ExtraSamples (VueScan, NegPy's own scanner output), multi-page TIFFs with a grayscale IR page (SilverFast iSRD), and _IR.tif sidecar files.
• Tooltips: added detailed tooltips to every sidebar control — sliders, buttons, dropdowns, and checkboxes. Controls with keyboard shortcuts show dynamic shortcut chips that update when bindings are customised.
• Optimizations: optimizations to preview loading speed. @reederphill
