## Which issue does this PR close? Closes #5436. ## Rationale for this change Allow top-level Variant scan output to use native columnar-to-row conversion when it is enabled. ## What changes are included in this PR? Preserve Variant field identity through JNI and write Spark's value-length/value/metadata layout. Nested Variant retains its existing fallback. ## How are these changes tested? Native layout tests and Spark 4.1 tests cover exact UnsafeRow bytes, nulls, buffer reuse, and canonical and shredded scans. Focused tests, Clippy, Scalastyle and formatting passed locally. Broader CI is pending. Please apply `run-all-spark-profiles` and `run-spark-4.1-tests`; I do not have label permissions. -- This is an automated message from the Apache Git Service.
