- Add explicit corner vertices of the inset boundary (w_frame offset) to Delaunay point set
- This guarantees no triangle can cross a boundary corner
- Updated test_data geometry files to v2.0 format with typed segments
- Sandbox 2 now has proper arc curves (4 arc segments) from extract_sandbox
- Preserved holes from v1.0 geometry
- Boundary vertices also enforced on keepout boundaries
profile_assembly.py now checks each pocket's polyline against the plate
boundary using Shapely contains(). Pockets extending outside are dropped.
Sandbox 1: 1 pocket removed (was crossing corner near x=150, y=-20).
Brain: profile_assembly.py now exports 'rib_web' — the actual material
geometry from Shapely boolean (exterior + interior rings). This is the
rib shape, not the pocket cutouts.
import_profile.py: prefers rib_web when available, drawing exterior +
interior polyline rings directly. Falls back to pocket-based drawing
for older rib JSONs without rib_web.
