LocalBackend is listed in __all__ but never imported at the top level, causing AttributeError on `from art import LocalBackend`. It cannot be imported eagerly because it depends on torch, transformers, and other heavy optional packages from the [backend] extra. Users should continue to use `from art.local import LocalBackend`. Also fix the LangGraph integration doc that used the broken `art.LocalBackend()` pattern.

Summary
LocalBackendfromart.__all__— it is listed but never imported, causingAttributeErroronfrom art import LocalBackendart.LocalBackend()patternBackground
LocalBackenddepends ontorch,transformers,numpy,aiohttp, and other heavy packages from the[backend]optional extra. Eagerly importing it inart/__init__.pywould break the lightweight client usage that only needsopenai,litellm,polars, etc.All existing code already uses the correct pattern:
LocalBackendwas the only orphaned entry in__all__— every other symbol has a matching import.Test plan
