### What problem does this PR solve? `VExpr::execute_column()` currently wraps a physically non-nullable result when the declared expression type is nullable, hiding output nullability mismatches. Remove that normalization so strict type checking reports these mismatches and CI can identify affected paths. The BE unit test now expects the mismatch error. ### Release note None ### Check List (For Author) - Test: Not run locally. Draft PR CI is intended to identify affected tests and execution paths. - Behavior changed: Yes. Nullable declarations with non-nullable physical results now return a type mismatch. - Does this need documentation: No -- This is an automated message from the Apache Git Service.
