- Add as_nanoarrow_array_stream, infer_geoarrow_schema, and as_arrow_table S3 methods for duckspatial_df. - Enable high-performance, zero-copy WKB streaming directly from DuckDB to Arrow/GeoArrow-compatible consumers. - Implement 'native = TRUE' path using geoarrow Arrow-to-Arrow kernels for optimized native geometry layouts without sf materialization. - Fix st_crs.duckspatial_df dispatch to correctly preserve SRID metadata. - Improve CRS detection in get_geometry_type_duckdb for robust DuckDB table creation. - Add comprehensive test suite for Arrow-native spatial pipeline.
