### What problem does this PR solve? Issue Number: None Related PR: apache#66363 Problem Summary: Successful delete bitmap cache checks repeatedly traversed both bitmaps to construct an unused error message, and nullable LARGEINT Arrow serialization formatted values before checking whether rows were null. Reuse the computed bitmap cardinalities, construct the mismatch message only on failure, and format LARGEINT values only for non-null rows. ### Release note None ### Check List (For Author) - Test: No need to test (control flow-only optimization; clang-format and git diff checks completed) - Behavior changed: No - Does this need documentation: No
