### What problem does this PR solve? Issue Number: None Related PR: None Problem Summary: VExpr::execute_column accepted a non-nullable column when the expression declared Nullable(T), even though DataTypeNullable requires a ColumnNullable representation. Remove this expression-only fallback so data type nullability and column nullability remain aligned. ### Release note None ### Check List (For Author) - Test: No need to test (pipeline validation requested) - Behavior changed: Yes (strictly enforce nullable column output matching) - Does this need documentation: No -- This is an automated message from the Apache Git Service.
