Support cloudflare wrangler

[bkniffler]

What is the problem this feature would solve?

Error when trying to use wrangler, e.g. to run a test for a cloudflare worker.

Message

[bun] Warning: worker_threads.Worker option "execArgv" is not implemented.

Code example

import {expect, test} from 'bun:test'
import {unstable_dev} from 'wrangler'
import {join} from 'path'

const root = join(__dirname, '../../..')
test('durable-objects', async () => {
  const handler  = await unstable_dev(join(root, 'src/index.ts'), {
    config: join(root, 'wrangler.toml'),
    experimental: {
      disableExperimentalWarning: true,
      disableDevRegistry: true
    },
    bundle: false,
    compatibilityDate: '2023-10-10',
    local: true,
    logLevel: 'debug',
  });
  const res =await handler.fetch('http://worker.dev', {});
  const json = await res.json();
  expect(json).toEqual({hello: 'world'});
});

What is the feature you are proposing to solve the problem?

Add support for execArgv and thus for wrangler.

What alternatives have you considered?

Use vitest/jest.

Still not working yet unfortunately, waiting for #8867 to work for unstable_dev, for anyone stumbling upon this

As well as #4165
