LangGraph agents using Chat Completions must explicitly persist their turns for conversation reloads. Add
storeLangGraphHistoryandlangGraphMessagesToItemsthrough@openuidev/server/langgraph, reusing the existing Chat Completions conversion and Conversations API writer.Accepts native BaseMessage instances from @langchain/core/messages and uses the package's message type guards. Preserves user text/images, assistant text, ordered tool calls and outputs; skips instructions. Supports the existing custom fetch/base URL options with @langchain/core as an optional peer required only for the LangGraph entry point. Includes a patch-release changeset for @openuidev/server 0.1.1.
First PR in the dependency chain. #1322 consumes this helper in the Cloud LangGraph template; #1321 is an independent featured-example picker PR based on main. The template dependency requires the server release before it can install from the registry.
Validation: server typecheck, build, ESLint, publint, and all 10 existing tests passed. Inline checks exercised real LangChain messages, tool roundtrips, images, empty input, request encoding and storage failure propagation. No test files were added.
