Commit Message

perf: collect engine-comparison Polars via streaming engine (DAL-276) (#294)

Bump the hash-pinned Polars wheels to 1.44.2 (the latest release; the
pyproject >=1.32,<2 range already admits it) and collect the Polars
engine-matrix adapter with engine="streaming" so the column measures
Polars' streaming execution path by default. Oracle-equivalence holds on
all six scenarios at 100k and 1M rows (rtol=atol=1e-10, equal_nan);
streaming is 1.4-2.1x faster on join/group_by/filter/projection at 1M
rows and 1.4x slower on sma20. The DataFusion pins stay at 54.0.0:
that is the latest datafusion-python release and it matches the core's
DataFusion major.
