Detect whether a space can be built as a clipped extrusion or needs
a B-rep fallback, based on wall face orientation and top/bottom
bounding planes.

get_vertical_bounding_planes always returns EXTRUDE_CLIP; the
EXTRUDE_CLIP-vs-BREP decision belongs to the calling layer.

Implement get_vertical_bounding_planes using ray-casting from the RL
cut elevation with nearest-hit and coplanar grouping.

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.
