Grid Alignment:
- Add edge-direction voting to align grid axes with dominant footprint edges
- Use length-weighted histogram binning (0.5° bins) for robust angle detection
- Re-extract footprint after frame rotation for coordinate consistency
- Falls back to min-rotated-rect → PCA if no dominant edge found
Gridfinity Profile Cutter:
- Add profile.py with Gridfinity chamfer specifications
- Implement stacked offset extrusions for chamfered sidewalls
- Use Shapely buffer with mitre joins for accurate geometry
- Union slabs via manifold3d when available
CLI Enhancements:
- Add --profile {rect,gridfinity,gridfinity_box} flag
- Add --profile-slices for controlling chamfer approximation
- Add --dump-mask for SVG debug output
- Add --require-intersect for strict bounds checking
- Enhanced verbose output with frame yaw and mask geometry
Tests:
- 11 new tests for edge voting alignment
- 25 new tests for profile and profiled cutter
