Wire a new "Export Geometry Database" tool button in AddModelDialog, adjacent to "Convert IFC File to Database", to produce a zipped read-only artifact combining a lossy RDB (with IfcRepresentationItem stripped) and a .ifcview geometry sidecar. Intended for cloud coordination workflows where parametric geometry editing is not needed. Pipeline changes to support this: - document_serializer_context gains a `skip_supertypes` field; the rdb plugin forwards it to RocksDbSerializer so the same registry path produces full or lossy RDBs. - Vertex quantization helpers (octEncodeNormal + quantizeVertex) move out of ViewportWindow.cpp into a shared header so the sidecar's byte layout stays identical regardless of whether it came from a GPU readback or a CPU pipeline. - New HeadlessSidecarBuilder runs a GeometryStreamer on the calling thread, captures MeshChunk/InstanceChunk into a SidecarData on the CPU, then computes georef + packed elements + LODs and writes the .ifcview — no ViewportWindow or GL context required. The Controller's export flow runs RDB conversion + sidecar build + QZipWriter packaging on a background QThread, writing through `<dest>.tmp` then renaming for atomic appearance in cloud-sync folders. ifcviewer-full now links Qt6::CorePrivate for QZipWriter.
