can_nest() only permitted IfcElement-to-IfcElement pairs, so nesting
two IfcElementType objects (e.g. an IfcElementAssemblyType nesting a
component IfcDoorType) was silently rejected. IfcRelNests.RelatingObject/
RelatedObjects are typed as the general IfcObjectDefinition in the
schema, so type-to-type nesting is schema legal, IfcOpenShell's core
nest.assign_object API already handles it generically, and the Nest
UI panel is driven purely by ifcopenshell.util.element.get_nest/
get_components (IFC data queries, not Blender collection structure),
so once the relationship exists it displays correctly with no other
changes needed.
Extended is_compatible_class to also accept a same-kind IfcTypeProduct
pair. Mixing an occurrence element with a type is intentionally still
rejected, that isn't a real modeling pattern.
Verified live in headless Blender: type-to-type nesting now creates
a real IfcRelNests and the Nest panel's own data functions reflect
it correctly; mixing an occurrence with a type is still rejected;
existing element-to-element nesting is unaffected.

Root cause: the IfcOpenShell-geometry-engine calculator ruleset
(IFC4QtoBaseQuantities.json and IFC4X3QtoBaseQuantities.json) left
IfcWall's GrossFootprintArea/NetFootprintArea mapped to null, so
these two quantities were silently omitted from Qto_WallBaseQuantities
whenever that ruleset was used. The generic gross_get_footprint_area
and net_get_footprint_area formulas already exist and are already
wired up for IfcSlab in the same files, so this was a missing mapping,
not a missing implementation.
Fixes#7029.

It was passing `IFC4X3` directly to `schema_by_name` which is expecting
schema identifier (e.g. IFC4X3_ADD2, not IFC4X3 allowed by `IFC_SCHEMA`
- IFC4X3 is one of the IFC4X3 iterations while it was in development,
not the final one).

This reverts commit b61f809731.
This commit was probably using not updated build, currently latest build is e333c1c and can confirm that it has `logger_or_root` added and `delete_same_facet_edge_pairs` removed.
AST parser has changed a bit and there are some minor differences in the
.py output. Updating files just to avoid seeing these diffs when
rerunning rule compiler.
Example error:
```
ast.Str(s=node.attr),
^^^^^^^
AttributeError: module 'ast' has no attribute 'Str'
```
`ast.Str` was deprecated since 3.8 and was removed in 3.14, see
https://docs.python.org/3/whatsnew/3.14.html#id9
Footings are authored two ways with different local axis conventions. Beam-like
footings (STRIP_FOOTING, FOOTING_BEAM) are a profile extruded along local Z, so
Length is local Z and the cross section sits on local X (Width, horizontal) and
local Y (Height, vertical). Slab-like footings (PAD_FOOTING, PILE_CAP) have their
footprint on local X/Y and their thickness (Height) on local Z.
The engine rule set is keyed per IfcFooting and cannot branch on predefined type,
so the previous static rule (Height=net_get_z, Length=net_get_max_xy, Width=null)
swapped Length and Height for beam-like footings and never emitted Width.
Add predefined-type-aware get_footing_length/width/height to the IfcOpenShell and
Blender calculators, and point the IfcFooting rule at them in all four IFC4/IFC4X3
ios/Blender rule files.
Confirmed by authoring footings through the real Bonsai generators and measuring
world-axis orientation: a beam-like footing with a 0.3 wide by 0.6 tall cross
section and 6.0 run reports Length 6.0, Width 0.3, Height 0.6, with the 0.3
physically horizontal and 0.6 physically vertical; a 2.0x1.5x0.3 pad reports
Length 2.0, Width 1.5, Height 0.3.

See #6835. Qto_OpeningElementBaseQuantities came out axis-scrambled for
openings authored in a Z-up local frame (X along the voided wall, Y
through it, Z vertical), which is how Bonsai authors every wall opening:
- The IfcOpenShell engine mapped Height to the local Y extent and Depth
to the local Z extent, so a 0.9 x 2.0 door opening with Bonsai's
default 1.2m void depth reported Height 1.2 and Depth 2.0, and Area
(max side area) picked the through-wall side, 2.4 instead of 1.8.
This matches the wrong Height=1.2/Area=1.2 screenshots reported for a
1x1 window opening in #6835.
- The Blender engine mapped opening Width to get_length, which returns
the longest bounding box edge, i.e. the opening height for typical
door openings (the same defect 4adaf0d fixed for IfcDoor Width), and
get_opening_depth used min(x, y), which returns the opening width
whenever the width is smaller than the void depth.
The IfcOpenShell engine now has opening-aware internal calculators
(get_opening_width/height/depth/area) that detect horizontal (slab
style) openings with the same heuristic as the Blender calculator, so
slab opening depths keep reporting the slab thickness. The Blender
ruleset uses get_x for opening Width, and get_opening_depth measures the
through-element Y extent for vertical openings.
Door and window quantities themselves are addressed separately: the
Blender engine door Width was fixed in 4adaf0d, and the remaining
door/window defects (door not quantified on the IfcOpenShell engine,
inflated areas) are fixed by the attribute-based calculators in #8389.
