IfcTriangulatedFaceSet/IfcPolygonalFaceSet were introduced in
Fix#7992: IFC4 and do not exist in IFC2X3. Previously, requesting an
IfcTessellatedFaceSet representation in an IFC2X3 file silently
fell back to a faceted brep after unassigning material sets.
Add a guard in the update_representation operator (user-facing
error) and in the add_representation API (ValueError) so the
unsupported request is caught instead of failing silently.

When validate_type selected a preferred_item from remaining_items
(e.g. the sole IfcBooleanResult in a representation), it left that
item in the list. The subsequent Items filter removed every item,
leaving Items=[] and causing guess_type to return
"MappedRepresentation" — silently corrupting the representation.
Also removes temporary debug print statements added during
investigation of the wall-to-slab extension workflow.

When a `+`-separated filter group returns no results, `FacetTransformer.facet_list`
was skipping the reset of `has_additive_facet_in_current_list` because the reset
was inside the `if self.elements:` guard. The stale flag caused the next group's
`add_default_elements()` to bail out early, leaving its element set empty and
silently dropping every subsequent group from the result.
Move the flag reset outside the guard so it always fires regardless of whether
the group produced any results.
add_railing_representation now factors into two parts:
* compute_wall_mounted_handrail_geometry returns a pure-geometry
WallMountedHandrailGeometry dataclass (handrail polyline + support
list + terminal caps), no IFC mutation.
* add_railing_representation wraps that dataclass into an
IfcShapeRepresentation as before.
Downstream consumers that want the same math without round-tripping
through an IFC file (Blender gizmo previews, viewport drafts) now
drive compute_X directly. Future add_X_representation work in the
geometry API is encouraged to follow the same shape — a sibling
compute_X function + thin IFC wrapper.
The railing_type parameter is dropped from the signature — only
WALL_MOUNTED_HANDRAIL was ever supported, so the kwarg was dead.
The Bonsai railing-modifier caller is updated in the same commit
to stop passing it; without that update Bonsai's
finish_editing_railing_path raises TypeError on the first edit.
RailingSupport and WallMountedHandrailGeometry use @dataclass(slots=True)
— they're constructed N-per-cap during arc sampling, so the per-instance
overhead matters.
Public symbols (RailingSupport, TERMINAL_TYPE,
WallMountedHandrailGeometry, compute_wall_mounted_handrail_geometry,
add_railing_representation) re-exported from ifcopenshell.api.geometry.
New test/api/geometry/test_add_railing_representation.py covers the
compute/wrap contract.

Drops the module-local ``mm()`` helper in favour of the centralised
``ifcopenshell.util.unit.mm_to_m`` (added earlier in this PR). The
``as mm`` import alias preserves the existing call sites' readability.

ShapeBuilder gains module-level NP_X / NP_Y / NP_Z / NP_XY / NP_XZ /
NP_YZ / NP_YX axis-index constants. Downstream geometry builders had
been redefining local copies for indexing np.ndarray vectors of shape
(3,) or (N, 3); centralising removes the duplication.
mep_transition_length and mep_transition_calculate verbose default
flipped from True to False. The prints are diagnostic-only output;
True-by-default spammed the console on every transition computation,
which fires per-fitting on IFC load.

Centralises the millimetre-to-metre conversion shortcut that
add_door_representation and add_window_representation each defined
locally. Subsequent commits in this PR switch both call sites to
import this from util.unit, removing the duplicate definitions.

Two upstream commits on this branch landed without updating all their
callers, leaving `import ifcopenshell.geom` unusable:
89c66f62b "Python import fixes: import from wrapper now which
inherits from mixins" moved the `file` class out of
ifcopenshell/file.py into ifcopenshell_wrapper, but missed
geom/main.py and stream.py which still did `from ..file import file`.
b022ca7e7 "Some plug-in work" dropped the SWIG exports for
`serialise`, `tesselate`, `XmlSerializer` (and other serializers)
with a `// @todo bring back serialization` marker, but left
geom/main.py referencing them at module-load time.
Fix the `file` imports to come from ifcopenshell_wrapper, and guard
the removed-serializer references behind `hasattr`, matching the
pattern already in use for the other optional serializers (gltf, hdf5,
collada, json, ttl). Revert once upstream fixes this.
IfcRelConnectsPathElements has an optional ConnectionGeometry attribute for
recording the geometric cut-plane between adjacent elements, but there was
no way to set it via the API.

assign_product creates IfcRelAssignsToProduct linking a structural member to
a physical building element. assign_to_building creates IfcRelServicesBuildings
linking a structural analysis model to a building. add_topology_representation
creates IfcTopologyRepresentation for structural elements, inferring the
representation type from the item class.

Both attributes are required by the IFC schema but were not settable via
the API function. Add physical_or_virtual and internal_or_external parameters
with "NOTDEFINED" defaults for backward compatibility. Update Bonsai boundary
panel to expose both fields in the editor.
