/**
 * A declarative `setInterval` hook that safely handles cleanup and React's closure staleness issues.
 *
 * @param callback - The function to execute.
 * @param delay - The delay in milliseconds.
 * @returns Object containing methods to stop, start, restart, and check the running status of the interval.
 *
 * @example
 * ```tsx
 * const [time, setTime] = useState(0);
 * const interval = useInterval(() => setTime(t => t + 1), 1000);
 * return <button onClick={interval.stop}>Stop Interval</button>;
 * ```
