The datamodel-v1.0 merge (cf05bbd1b) overwrote build_rocky.yml with a
version that switched python3 -> uv run but dropped the --shared flag that
a91b1da28 ("Reduce Rocky package size") had added. build_osx.yml kept it
(ddee88bed).
Without --shared, nix/build-all.py builds IfcOpenShell as static libs, so
each of the ~40 plug-in .so files (schemas x8, kernels, mappings,
serializers, writers) statically embeds a full copy of libIfcParse +
libIfcGeom. The data-model rewrite made those base libs much larger, so the
duplication ballooned the Linux packages (~2-3x). With --shared the plug-ins
dynamically reference the shared libIfcParse/libIfcGeom instead. Restores the
same size reduction macOS already has.
