Rewrite the langgraph-js agent to use `createAgent` from `langchain`
(matching langgraph-python) with `copilotkitMiddleware` and
`stateStreamingMiddleware` from `@copilotkit/sdk-js/langgraph-middlewares`.
Tools now use `ToolRuntime` for state and tool-call-id access. System
prompt inlined in `agent.ts`; drop the file-based `PROMPT.md`.
Replace the legacy single-stage Dockerfile with a Node-only two-stage
build that mirrors the langgraph-python Dockerfile (frontend build →
runner, HttpAgent route override for Docker, Turbopack→webpack).
Add JS-specific `entrypoint.sh` (launches `@langchain/langgraph-cli dev`
+ Next.js standalone) and `docker-compose.test.yml` (wget healthcheck
for the alpine-based agent image, STARTER=langgraph-js default). Both
added to the instance's `allowedDivergence` in the parity manifest.
Rewrite the README to drop Python/uv prerequisites and list the correct
TypeScript tool paths.
- chmod +x all new .sh scripts so they work on Linux/macOS
- Use --ignore-scripts in langgraph-js Dockerfiles to avoid postinstall
failure (agent/ dir not yet copied during npm install stage)
- Install agent deps in production Dockerfile after COPY agent/
- Fix hardcoded pnpm commands in agent-spec README
Flatten langgraph-python, langgraph-js, and mcp-apps starters so
npm install && npm run dev works out of the box. Replace Turborepo
with concurrently, move apps/* to root, update Dockerfiles, READMEs,
and entrypoints. Also remove stray pnpm-lock.yaml from a2a-a2ui and
ms-agent-framework-dotnet starters.
