fix(sdk): normalize HITL edit decisions for Python servers

`StreamController.respond()` now mirrors camelCase and snake_case on
edit
decisions (`editedAction` / `edited_action`) so JS clients can resume
    human-in-the-loop interrupts against Python LangGraph servers.

Assistant-UI Claude Example

This example combines:

  • @assistant-ui/react for the Claude-style chat surface
  • @langchain/react for streaming LangGraph state on the frontend
  • a basic langchain agent on the backend

What it shows

  • A Claude-inspired assistant-ui thread and composer
  • A local single-agent graph powered by langchain
  • How to bridge @langchain/react state into assistant-ui with useExternalStoreRuntime

Setup

Create a local .env file in this folder with:

OPENAI_API_KEY=your_openai_api_key
OPENAI_MODEL=gpt-4.1-mini

Optional overrides:

LANGGRAPH_API_URL=http://localhost:2024
VITE_LANGGRAPH_API_URL=http://localhost:2024
VITE_LANGGRAPH_ASSISTANT_ID=assistant-ui-claude

Run

pnpm --filter @examples/assistant-ui-claude dev

Then open the Vite URL shown in the terminal, usually http://localhost:5173.

The frontend talks directly to the LangGraph dev server at http://localhost:2024, which serves the local assistant-ui-claude graph from langgraph.json.
