Re-export is_anthropic_model_name from langchain utils

Expose the helper via uipath_langchain_client.utils alongside other
re-exported core utilities (exceptions, RetryConfig). Internal callers
now import from the package-local utils module instead of reaching
across to uipath.llm_client.utils.model_family directly.
