Express integration

On a plain Express app, build a CopilotRuntime with createKabooRunner(store) and mount CopilotKit's Express handler. The runner ships no HTTP layer, so this is the whole integration:

import express from "express";
import { CopilotRuntime } from "@copilotkit/runtime/v2";
import { createCopilotExpressHandler } from "@copilotkit/runtime/v2/express";
import { createKabooRunner, InMemoryThreadStore } from "@pgege/kaboo-runtime";

const runtime = new CopilotRuntime({
  agents: {},
  runner: createKabooRunner(new InMemoryThreadStore()),
});

const app = express();
app.use(createCopilotExpressHandler({ runtime, basePath: "/api/copilotkit" }));

const port = Number(process.env.PORT ?? 4000);
app.listen(port, () => {
  console.log(`CopilotKit runtime on http://localhost:${port}/api/copilotkit`);
  console.log("kaboo-runtime persistence: InMemoryThreadStore");
});

For durable persistence, swap in new PostgresThreadStore({ dsn }) — see examples/express-postgres. Add your real agents to the agents map (e.g. an HttpAgent pointing at a kaboo-workflows pipeline).
