Add comprehensive selection refinement tools for precise selection editing. Features: - Expand selection by N pixels using dilation algorithm - Contract selection by N pixels using erosion algorithm - Feather selection with Gaussian blur - Invert selection (already existed) - All operations work on selection mask data - Morphological operations: * Expand: Dilate mask by checking max neighbor values * Contract: Erode mask by checking min neighbor values * Feather: Apply separable Gaussian blur (horizontal + vertical) Changes: - Updated store/selection-store.ts with three new functions: * expandSelection(pixels) - Dilate selection * contractSelection(pixels) - Erode selection * featherSelection(radius) - Gaussian blur - Implements proper image processing algorithms - Works on Uint8Array mask data - Updates feather property in selection 🤖 Generated with [Claude Code](https://claude.com/claude-code) Co-Authored-By: Claude <noreply@anthropic.com>
