Part.Intersects now filters out intersection points that coincide with
vertices of both perimeters (shared corners/endpoints), which are touch
points rather than actual crossings. Plate.HasOverlappingParts adds a
bounding box pre-filter requiring overlap region to exceed Epsilon in
both dimensions before performing expensive shape intersection checks.
