Clustering issue: missing file

[joannacknight]

The code on the main branch ran successfully over the weekend for distilbert and EmbeddingGemma.

However, I then tried to run the test search functionality using the distilbert data, and got this error:

open ../data/c1970a4c-46c4-8fbe-cf94-d099e24ba206-None-192/clusters/cluster_2064.txt: no such file or directory

The file cluster_2064.txt didn't exist, but cluster_2063.txt and cluster_2065.txt both did exist - so it looks like a value has been skipped somewhere.
