I changed `WithScanPlanningMode` to return a `ScanOption` closure and defer the `panic("unimplemented")` until the option is applied. That keeps option construction consistent with the existing `ScanOption` helpers and preserves the no-behavior-change claim for eagerly built option slices. -- This is an automated message from the Apache Git Service.
