Function set_geometry

native/watchos/src/scene.rs:276–286

TS → native FFI layout: 12 f64s per vertex — xyz, nx ny nz, rgba, uv. Color is ignored (material color wins via bloom_scene_set_material_color). Directly install pre-decoded geometry (from a loaded model) into a scene node, bypassing the 12-f64-per-vertex TS FFI layout.
