fix(compute): suppress S6218 on the internal CodeTable carrier

Sonar flags the boolean[] record component (array reference equality in
the generated equals/hashCode). CodeTable is a private data carrier
that flows from the predicate lowering to the scan loops and is never
compared — the same justified suppression the array-holding
ChunkedXxxArray records already carry.
