Mirror the XPU device-detection block vectorize-io#2260 added to LocalSTEmbeddings into the byte-identical LocalSTCrossEncoder twin, so the local reranker also uses Intel Arc XPU instead of silently falling back to CPU. Guarded by hasattr(torch, 'xpu') + is_available(); no-op on CUDA/MPS/CPU.

#2260 added Intel XPU device detection to
LocalSTEmbeddings.initialize()(embeddings.py) but the byte-identical sibling block inLocalSTCrossEncoder.initialize()(cross_encoder.py) was left untouched. On an Intel Arc box, embeddings now run on XPU while the local cross-encoder reranker silently falls back to CPU.This mirrors #2260 exactly into the cross-encoder: the XPU probe is guarded by
hasattr(torch, "xpu")+torch.xpu.is_available()inside the existing try/except, so it is a no-op on all current CUDA/MPS/CPU hardware and cannot regress them.Follow-up to #2260.
