Increase default timeout for `task.result`

[janwilmake]

It's bad DX having to specify this and confusing we already have a timeout parameter (in seconds) and the SDK also needs a timeout parameter (in ms)

const runResult = await client.taskRun.result(
  taskRun.run_id,
  {
    timeout: 3600,
  },
  { timeout: 3600 * 1000 }
);

It's best if the default timeout becomes 3600 so people or llms won't make the mistake by default.

Seems we can configure this: https://www.stainless.com/docs/reference/config#client-settings

Edit: it seems we are still running into timeouts even with above code!
