What changed
RecordBatch::from_pyarrow_boundnow returns aPyValueErrorwhen a PyArrow C array capsule contains a nullable top-levelStructArray, instead of panicking via an internal assertion.A regression test covers importing a nullable PyArrow struct array through the capsule path.
Why
This conversion handles external Python input, so unsupported nullable struct arrays should surface as Python exceptions rather than aborting through a Rust panic.
