EntityProcessingPipelineFactoryTest

Guards the cache-generation pipelines against drifting apart.

Runner::getReflection() once built its storage manager with the default empty pipeline while run-reflection-processor.php installed ReflectionDeduplicationProcessor, so a Runner-triggered regeneration silently wrote a non-deduplicated cache over the committed file. Both paths now build their pipeline here, and these tests assert the deduplication processor is actually present.
