An SI prefix attaches to the base unit symbol and the prefixed symbol is
raised to the power as a whole: DECI CUBIC_METRE is dm3 = a litre = 1e-3 m3,
not 0.1 m3. The scale factor previously applied the prefix multiplier
linearly for all IfcSIUnits, inflating volumes x100 and areas x10 for such
declarations (produced e.g. by MagiCAD for Revit MEP exports).
Following the reviewer note in #9278, the exponent is taken from the
derived attribute IfcSIUnit.Dimensions rather than from substring matching
on the unit name: the multiplier is raised to LengthExponent only when the
unit's dimensions are a pure power of length, so prefixed derived units
(KILO PASCAL, MEGA NEWTON) and non-length units (KILO GRAM) correctly keep
the linear multiplier. This matches the exponent handling already present
in convert() and named_dimensions in the same module.
Adds regression tests for prefixed AREAUNIT/VOLUMEUNIT and for the
linear-prefix behaviour of PRESSUREUNIT/MASSUNIT.
Return independent geometry copies with unique ownership, preserve parent lifetimes, and teach the Python wrapper to own derived results. Keep serializer inputs non-owning and replace Collada's deferred object with copied triangulation elements.\n\nGenerated with the assistance of an AI coding tool.

To fix wrapper depending on `ifcopenshell.geometry.kernel.opencascade.so` plugin, which breaks wasm module import (wrapper imported first and it fails because occt kernel isn't loaded yet and loading kernel first since it needs some symbols from the wrapper).
`geometry_serializer` seems to need `OpenCascadeConversionResult.h` from the kernel just to be able to refer to structs (`ConversionResultShape`, `OpenCascadeShape`) and include with relative path already allows it.
