Given the tables hashref from DBIO::DB2::Introspect::Tables, returns a hashref keyed by table name. Each value is an arrayref of column hashrefs in COLNO order with keys: column_name, data_type, not_null, default_value, is_pk, pk_position, size. is_auto_increment is set (to 1) only for GENERATED ... AS IDENTITY columns, matching the canonical model shape consumed by "table_columns_info" in DBIO::Introspect::Base.
