```
close(Control)
-spec close(t()) -> ok | {error, map()}.
```

Retire this control client and its helper without issuing session or daemon destruction commands. Native lifetime policies and detachment hooks may still change state; cleanup does not reverse their effects. Returns ok only after actual retirement. A finite cleanup failure leaves a supervised owner for retry and observation. Successful close is idempotent during the 60-second handle retention period.

## Parameters

- `Control` (`t()`)
