load_predicted_local now reads predict parquet via a lazy polars scan with column projection pushed into the reader, instead of materializing the whole file as a pandas DataFrame. Also adds marginal_table_pl and constraint_report_pl, polars-native duplicates that read straight from a predict parquet path/LazyFrame and stay lazy per (group, dim) pair, so peak memory is one column slice rather than the whole SampleCollection.
