Expand description

Build a Google-Earth-ready KMZ (doc.kml + model.dae) directly from the viewer’s already-produced (Y-up) meshes, the working path (#1427). The model is embedded as COLLADA (the only <Model> format Google Earth loads), with emission-lit, double-sided materials and clampToGround placement. Mesh arrays match crate::try_export_collada_from_meshes / export_glb_from_meshes.

Fails closed when the embedded COLLADA would carry no geometry: the archive this used to ship around a schema-invalid document was read as success by every caller. See crate::try_export_collada_from_meshes for the two inputs that reach that state.
