### Description

TestFloatVectorSimilarityQuery.testTimeout fails non-deterministically (10 out of 50) on main in Linux:

### Steps to reproduce

```
./gradlew test --tests TestFloatVectorSimilarityQuery.testTimeout -Dtests.seed=9843678908EBB30D -Dtests.multiplier=3 -Dtests.locale=ru -Dtests.timezone=America/Manaus -Dtests.asserts=true -Dtests.file.encoding=UTF-8 -Ptests.iters=50
```

### Version and environment details

```
$ uname -a
Linux ip-172-31-6-75 6.8.0-1025-aws #27-Ubuntu SMP Wed Feb 19 19:10:47 UTC 2025 x86_64 x86_64 x86_64 GNU/Linux
```

Start with TestFloatVectorSimilarityQuery.testTimeout and the failing assertion at BaseVectorSimilarityQueryTestCase.java:508. Reproduce it with the provided ./gradlew command and seed, then trace the timeout test behavior. Done means the test no longer fails intermittently under the reported Linux reproduction.
