Claude Code ring bell on any kind of stop without explicitly enabling alarms

Right now there are two paths to get a notification when Claude Code has stopped for some reason:

- explicitly turn on the alarm which is looking for visual changes
- follow the workaround in https://github.com/anthropics/claude-code/issues/36850 to send terminal bells on stop

```json
"hooks": {
"Notification": [
{
"hooks": [
{
"type": "command",
"command": "printf '\\a' > /dev/tty 2>/dev/null || true"
}
]
}
],
"Stop": [
{
"hooks": [
{
"type": "command",
"command": "printf '\\a' > /dev/tty 2>/dev/null || true"
}
]
}
]
}
```

Ideally we should work out of the box, and the user shouldn't have to turn anything on at all...

El issue no menciona archivos ni pruebas. Empieza localizando la gestión existente de alarmas y notificaciones en el código TypeScript y compárala después con el workaround de Notification y Stop hook del issue #36850. Se considera terminado cuando suenen campanas de terminal en cada Claude Code stop sin que los usuarios tengan que habilitar explícitamente las alarmas.
