Pull request overview

Adds Apache Arrow batch support for executeBulkUpsert by introducing an extensible BulkUpsertData abstraction and an ApacheArrowWriter to build Arrow-encoded batches, with unit/integration tests to validate schema mapping and end-to-end upserts.

Changes:

• Introduce BulkUpsertData as an interface with concrete implementations for Proto rows, CSV, and Arrow batches.
• Add ApacheArrowWriter for building Arrow schema + record batches for bulk upsert.
• Add/adjust unit + integration tests and Maven dependencies/profiles for Apache Arrow.
