Parent: #589 iceberg-go's iceberg-to-arrow converter wraps `UnknownType` in an Opaque extension type around `arrow.Null`. pyiceberg maps it to plain `pa.null()` instead. Mirror pyiceberg's posture so the cross-client wire format on Arrow records matches. Two pieces: 1. Forward (iceberg → arrow): drop the `OpaqueType` wrapper in the `convertToArrow.VisitUnknown` visitor; emit plain `arrow.Null`. 2. Reverse (arrow → iceberg): no case for `*arrow.NullType` in the `convertToIceberg` switch over Arrow types. Add it; map to `iceberg.PrimitiveTypes.Unknown`. Tests cover round-trip in both directions. Watch for any callers that depend on the Opaque wrapper's extension metadata; if they exist, this is a small breaking change worth calling out in the PR. -- This is an automated message from the Apache Git Service.
