Introduce polars_bio/_streaming.py with make_streaming_source, StreamingConfig, PredicatePushdownConfig, pyarrow_schema_to_polars_dict, and extract_column_names. Refactor io.py, pileup_op.py, range_op_io.py, and utils.py to use the shared helpers, removing duplicated streaming logic and the tqdm dependency from each call-site.
