> Each columnar decompressor (PassThrough, RunLengthEncoding,
> DictionaryEncoding, BooleanBitSet, IntDelta, LongDelta) repeats the same
> two-line idiom to build the nulls buffer:
> buffer.duplicate().order(ByteOrder.nativeOrder()) followed by rewind(). This
> extracts a protected createNullsBuffer(buffer) helper on the shared Decoder
> trait and routes the six call sites through it. No behavior change; it also
> normalizes one site that called rewind without parentheses.
