## Human Summary
langchain-huggingface 1.2.3 hides API tokens from string representations, adopts device-agnostic accelerator detection via torch.accelerator, drops the retired IPEX backend, and updates multiple dependencies.

## Agent Summary
langchain-huggingface==1.2.3 masks huggingfacehub API tokens in repr outputs, replaces custom device detection with torch.accelerator, and removes the deprecated IPEX backend alongside numerous dependency updates.

## Body
The langchain-huggingface package has released version 1.2.3. Key functional updates include masking the Hugging Face Hub API token in object representation strings (repr) to avoid accidental credential leaks, transitioning device count detection to torch.accelerator for hardware-agnostic execution, and removing the retired IPEX backend. The release also incorporates numerous dependency and lockfile bumps across langgraph-sdk, transformers, torch, langsmith, and supporting utilities.

## Recommended actions
- Upgrade to langchain-huggingface==1.2.3.
- Remove any configuration relying on the retired IPEX backend if applicable.
- Verify compatibility with updated dependency requirements including PyTorch and transformers.
