If the spinner drops out prematurely, input is invisible

[flippedcracker]

Describe the bug
If I start a spinner and something exits out (like a os.Exit() or log.Fatal() ), then the input in the terminal is hidden. The only way to get it back is to reset terminal

To Reproduce
Steps to reproduce the behavior:

1. Start a spinner
2. exit out of the spinner Action function by way of os.Exit or log.Fatal
3. try to type in the terminal
4. see the nothing shows in the terminal

Expected behavior
Exiting out should return to terminal as normal

Hey, can you confirm that this is a different issue than #159?

If so, we can combine the issues for some clean up. Otherwise, thank you so much for the issue!

[caarlos0]

can you share a reproducible?

[flippedcracker]

Here is a basic reproducible

`package main

import (
	"fmt"
	"log"
	"os"
	"time"

	"github.com/charmbracelet/huh/spinner"
)

func main() {
	err := spinner.New().
		Title("Doing something in the background").
		Action(func() {
			time.Sleep(5 * time.Second)
			fmt.Println("The something failed")
			os.Exit(1)
		}).Run()
	if err != nil {
		log.Fatal(err)
	}
}`

ah, yes, the problem is the Exit(1)

Exit skips all defers and what not, so there's not anything we can do here I think https://pkg.go.dev/os#Exit

We need better ways to handle this, I think #292 is a good start, as you can make an action that returns an error for example.

fwiw with #292 you can do something like:

package main

import (
	"context"
	"errors"
	"log"
	"time"

	"github.com/charmbracelet/huh/spinner"
)

func main() {
	err := spinner.New().
		Title("Doing something in the background").
		ActionErr(func(context.Context) error {
			time.Sleep(1 * time.Second)
			return errors.New("something went wrong")
		}).Run()
	if err != nil {
		log.Println(err)
	}
}
