- Fixed dimension mismatch between mask and display image after undo
- Mask was being created at original image size, but displayImage is at
preview scale after undo/redo (renderPreview scales images > 2048px)
- Now create mask at actual displayImage dimensions, ensuring mask and
image sizes match for inpainting
- Also fixed edge refinement gradient to recompute when image changes
- Add LaMaFP16_512.mlpackage (~90MB) for high-quality object removal
- Add LaMaInpainter.swift wrapper with image preprocessing and merging
- Modify InpaintEngine to use LaMa first, gradient fill as fallback
- Fix brush mask size (use scale 1.0 instead of screen scale)
- Fix LaMa output size (use scale 1.0 in merge function)
- Add model loading wait with 5 second timeout
The LaMa model provides significantly better inpainting quality compared
to the gradient fill method, especially for complex backgrounds.
- Fix object selection by correctly calculating bytesPerPixel in mask buffer
- Improve inpainting with 16-direction gradient fill and inverse-square blending
- Add 100 smoothing iterations to eliminate seam artifacts
- Increase mask dilation to 20px to exclude object edge remnants
- Fix brush tool gesture conflict - disable pan while brushing
- Fix image orientation by normalizing EXIF rotation on load
Modified files:
- MaskingService.swift: Fix pixel offset calculation for mask buffers
- Shaders.metal: Add gradient fill with 16 directions and multi-pixel sampling
- PatchMatch.swift: Use gradient fill + smoothing, add encodeGradientFill
- InpaintEngine.swift: Increase iterations to 500, patch radius to 8
- CanvasView.swift: Disable pan gesture when brush tool selected
- EditorViewModel.swift: Normalize image orientation on load
The DragGesture with minimumDistance: 0 for line brush mode was
consuming all touches, preventing tap detection for Object/Person/Wire
tools. Fixed by:
1. Only attaching line brush gesture when in line brush mode
2. Added conditional .if() view modifier extension
3. Added debug logging to tap gesture to track gesture flow

Scale mask and image to texture dimensions when loading into Metal
textures, fixing crash when brush mask has different dimensions
than the source image.

- Edge refinement: Wire toggle to actually snap brush strokes to edges
using Sobel gradient analysis in EdgeRefinement.swift
- Brush preview circle: Show visual cursor following finger during drawing
- PHAsset storage: Capture localIdentifier for Photo Library imports
- Low-confidence mask warning: Show "Does this look right?" for uncertain
detections based on mask coverage and edge sharpness analysis
- Fix Swift 6 concurrency warnings with nonisolated static methods

Update MaskOperation to store mask dimensions for reconstruction.
Implement proper operation rendering in ImagePipeline:
- Apply mask+inpaint operations with proper mask reconstruction
- Handle adjustment operations by type (brightness/contrast/saturation)
- Scale masks when rendering previews at reduced resolution

- Add EditorViewModel coordinating masking, contour detection, and inpainting
- Connect PhotoEditorView to viewModel with mask confirmation bar
- Add processing overlay and error toast UI
- Update CanvasView with tap-to-mask functionality
