Move Blender-independent space generation algorithms from Bonsai (GPL) to ifcopenshell.util (LGPL): - ifcopenshell.util.shape.bisect_mesh_plane_vf: vectorized numpy triangle/plane intersection for mesh bisection - ifcopenshell.util.element.iter_top_connections: walker for IfcRelConnectsElements(TOP) relationships - ifcopenshell.util.space: new module with get_boundary_lines, get_space_polygon, get_auto_space_height and height detection helpers — all operating on IFC geometry without Blender Bonsai's tool/spatial.py now delegates to these utilities via thin wrappers, keeping only Blender-specific concerns (cache management with depsgraph invalidation, UI property reads). tool/wall.py iter_wall_slab_connections delegates to ifcopenshell.util.element.iter_top_connections. Added 22 tests: 6 for bisect_mesh_plane_vf, 10 for space generation algorithms, 4 for iter_top_connections, 2 Bonsai integration tests for cache behavior. Generated with the assistance of an AI coding tool.
