### What problem does this PR solve? Issue Number: None Related PR: #66204 Problem Summary: ColumnVariantV2 is implemented in master but remains opt-in through Config.enable_variant_v2, so normal Variant planning and storage continue to select the legacy path. Make the existing V2 path the default while preserving enable_variant_v2=false as an explicit fallback. Keep the hierarchical iterator test portable across standard library implementations. ### Release note Enable ColumnVariantV2 by default for Variant execution and storage. The legacy path remains available with enable_variant_v2=false. ### Check List (For Author) - Test: FE ConfigTest (7/7); BE focused tests (78/78); clang-format; check-format; git diff --check - Behavior changed: Yes (ColumnVariantV2 is enabled by default; explicit false remains supported) - Does this need documentation: No -- This is an automated message from the Apache Git Service.
