polygonize() previously checked only raster.ndim != 2. Non-DataArray inputs raised AttributeError on .data; complex dtypes failed inside numba with confusing errors. The optional mask was not validated. - Add _validate_raster on raster (numeric, ndim=2). - Add _validate_raster on mask (numeric=False so bool mask works). 4 new tests in TestPolygonizeInputValidation.
