[JS] missing uuid import on 0.9 RC

[cabljac]

Describe the bug

Running a simple flow in Next.js (in a test) it complained about missing uuid.

I'm not 100% this is a genkit issue, but my flow was just this:

import { z } from "genkit";
import { ai } from "../genkit";

export const mainFlow = ai.defineFlow(
  {
    name: "mainFlow",
    inputSchema: z.string(),
    outputSchema: z.string(),
  },
  async (input) => input
);

and my test:

import { describe, it, expect } from "vitest";
import { mainFlow } from "./mainFlow";

describe("mainFlow", () => {
  it("should run", async () => {
    const result = await mainFlow("hello");
    expect(result).toBe("hello");
  });
});

Expected behavior
Not to need to install uuid as a dependency, probably

We found we needed to add uuid during testing in this update as well
