fix: prevent ring index overflow

[POABOB]

I added these lines to prevent the ring index from overflowing.

// Add adds v into r.
func (r *Ring) Add(v any) {
	r.lock.Lock()
	defer r.lock.Unlock()

	r.elements[r.index%len(r.elements)] = v
	r.index++

	// prevent ring index overflow
	if r.index/len(r.elements) >= 2 {
		r.index = r.index - len(r.elements)
	}
}

The issue is from #2627.
