PORT env variable bug

[yigit353]

If you set PORT variable in .env file to anything other than 8000 you fail because of the route.ts looks for REMOTE_ACTION_URL and if it is not found it defaults to 8000 port here:

const runtime = new CopilotRuntime({
  remoteEndpoints: [
    {
      url: process.env.REMOTE_ACTION_URL || "http://localhost:8000/copilotkit",
    },
  ],
});

It should be documented and also maybe find a more elegant solution.

Cheers.
