Summary
AI summaryAdds an optional compiled runtime with native Arrow Column and CSV transform pipeline.
Full changelog
Optional compiled runtime for GoldenFlow. First publish since 0.15.0, bringing the Polars-eviction columnar substrate to PyPI (0.16-0.24): arrow-free list chain + native Arrow Column (pyarrow-free); native CSV transform pipeline (parallel read/write, Polars-matching float formatter); auto-routed total/nullable string chains; numeric columnar execution (f64 + i64 parsers + array ops, CSV + in-memory); multi-output splits. Byte-identical to the Polars engine, parity-gated; older callers degrade gracefully via capability probes.
