### Rationale for this change Arrow IPC Messages wrap RecordBatch data in a Message flatbuffer which has a custom_metadata field (vector of KeyValue pairs). PyArrow and other implementations use this to attach per-batch metadata, but the Go implementation previously ignored it on both read and write paths. ### What changes are included in this PR? Add a RecordBatchWithMetadata optional interface to avoid breaking the existing RecordBatch interface. The simpleRecord implementation carries metadata through NewSlice, SetColumn, and IPC round-trips. Includes PyArrow-generated test fixtures for interoperability validation. ### Are these changes tested? Yes tests are included. ### Are there any user-facing changes? Yes custom_metadata is now supported on RecordBatches. This change was developed with AI assistance and manually reviewed. -- This is an automated message from the Apache Git Service.
