### What's changed - Backport the projected shredded Variant exchange and TopN fixes from #66446. - Let the Paimon native Parquet reader interpret schema-matched, unannotated Variant carriers without misclassifying ordinary structs. - Preserve native projection and predicate pruning for shredded Variant leaves, including mixed shredded and unshredded files. - Keep lazy Variant reconstruction counters alive after scanner profile destruction. - Add schema, reader, lifecycle, mixed-layout, native/JNI, subpath, null, array, and predicate coverage. ### Tests - Focused ASAN unit test binary: 187 tests passed. - FE Release build and Checkstyle passed. - BE Release compilation passed. - `test_paimon_catalog_variant` regression suite passed with both JNI and native reads. -- This is an automated message from the Apache Git Service.
