When intra-merge parallelism was introduced, the validation that numWorkers must ==1 with a null executor service was removed from Lucene99HnswVectorsFormat. However, I forgot to remove that validation from Lucene99HnswScalarQuantizedVectorsFormat. This corrects that mistake, allowing Lucene99HnswScalarQuantizedVectorsFormat and Lucene99HnswVectorsFormat to take advantage of the merge-schedulers intra-merge threading.

Building
Basic steps:
- Install OpenJDK 21.
- Clone Lucene's git repository (or download the source distribution).
- Run gradle launcher script (
gradlew).
We'll assume that you know how to get and set up the JDK - if you don't, then we suggest starting at https://jdk.java.net/ and learning more about Java, before returning to this README.
