[Request] Grouped spinners?

[JoshuaKGoldberg]

Is your feature request related to a problem? Please describe.

Grouping (https://github.com/natemoo-re/clack/tree/24a3f4a20019c7dad2f69bcf163a8b5a3f747a16/packages/prompts#grouping) is available right now for prompts, but not for spinners. But I'd like to group the spinners together too: having a parent task and sub-task.

Describe the solution you'd like

Could we add a new spinner API analogous to p.group? Maybe, p.spinnerGroup?

await p.spinnerGroup("Outer group", [
  ["First sub-task", async () => { /* ... */ }],
  ["Second sub-task", async () => { /* ... */ }],
  ["Third sub-task", async () => { /* ... */ }],
]);

Describe alternatives you've considered

In JoshuaKGoldberg/create-typescript-app#708 -> JoshuaKGoldberg/create-typescript-app#710 I kind of did it manually, wrapping around Clack. It's not great.

Additional context

I'd be happy to contribute this, or if you don't want to keep it as a core feature, publish it as a standalone helper package.

@cpreston321 that PR doesn't resolve this issue though. It just runs s.start and s.stop around the tasks. This issue is for nesting tasks within the spinners.

@JoshuaKGoldberg Got it, i reopened the issue.

So if task 1 completes it moves to task 2.. Let's say if task 2 fails does that kick out of the task process / cancel the spinner ?

Also if it easier you can create a draft pull request with some examples. I think for this functionality we can keep this at the @clack/prompt level. I think in the future we can think more of creating standalone helper primitives in a separate package.

I would think so, yeah. At least by default. Maybe there could be an API option for whether to bail or continue?

Yes! #158 is roughly what I was thinking of. I haven't put too much thought into the API design, pending posting here.
