### Description Off-heap scoring for quantized vectors! Related to #13515 This scorer is in-line with [`Lucene99MemorySegmentFlatVectorsScorer`](https://github.com/apache/lucene/blob/77f0d1f6d6762ca6ac9af5acc0c950365050d939/lucene/core/src/java24/org/apache/lucene/internal/vectorization/Lucene99MemorySegmentFlatVectorsScorer.java#L30), and will automatically be used with [`PanamaVectorizationProvider`](https://github.com/apache/lucene/blob/77f0d1f6d6762ca6ac9af5acc0c950365050d939/lucene/core/src/java24/org/apache/lucene/internal/vectorization/PanamaVectorizationProvider.java#L30C13-L30C40) (i.e. on adding `jdk.incubator.vector`). Note that the computations are already vectorized, but we're avoiding the unnecessary copy to heap here.. I added off-heap Dot Product functions for two compressed 4-bit ints (i.e. no need to "decompress" them) -- I can try to come up with similar ones for Euclidean if this approach seems fine.. -- This is an automated message from the Apache Git Service.
