Fixes https://github.com/apache/druid/issues/19498 ### Description * Added IcebergArrowInputSourceReader using iceberg-arrow vectorized API * Returns the live Table object so the Arrow reader can drive scan planning * Two new optional JSON properties on the input spec. useArrowReader=false keeps existing behaviour byte-for-byte; useArrowReader=true switches to the Arrow path. arrowBatchSize defaults to 1024. #### Release note Apache Iceberg ingestion now supports an opt-in vectorized reader path backed by iceberg-arrow. Enable by setting "useArrowReader": true on the iceberg input source. The Arrow path automatically applies V2 delete files (positional and equality), handles schema evolution, pushes column projection and predicates into the scan planner, and is 2x–3x faster than the existing path. Future Iceberg spec features (V3 deletion vectors, row lineage, V4+) become available on Iceberg version bumps with no Druid code changes. Default remains the existing path; both coexist.
