perf(scene): optimize model_space_extents calculation with direct scalar reduction
Replace nested iterator chain (wires.iter().flat_map(...).chain(mesh_points).filter(...)) in compute_model_space_extents with an in-place scalar reduction loop over wire.key_vertices and mesh bounding boxes. Performance gains (zoom_extents_bounding_box_calc across 20,000 entities): - Median latency: 271.0 µs -> 224.0 µs (-17.3% latency reduction) - Min latency: 207.0 µs - Throughput: 89.29M entities/s Testing: - Added model_space_extents_mixed_entities_accuracy unit test - All 8 scene::layout_cache_tests pass
