Issue: moveend Event Triggered by zoomToBounds Even Without Bounds Change

Bug Report: moveend Event Triggered by zoomToBounds Even Without Bounds Change

Description:
The moveend event is being fired when calling zoomToBounds even though the map's visible bounds have not changed. This behavior is causing unnecessary updates and performance issues.

Steps to Reproduce:

1. Create a map with clusters using Leaflet.markercluster.
2. Call the zoomToBounds method on a cluster.
3. Observe that the moveend event is fired even if the map's visible bounds remain the same.

Expected Behavior:
The moveend event should only be fired when the map's visible bounds have actually changed.

Suggested Fix:
Modify the _moveEnd method in src/MarkerClusterGroup.js to check if the map's visible bounds have actually changed before performing updates.

JS Fiddle:
Please look into this https://jsfiddle.net/4r8k9hLj/14/.

Example Code:

_moveEnd: function () {
    if (this._inZoomAnimation) {
        return;
    }

    var newBounds = this._getExpandedVisibleBounds();

    // Check if the map has visibly moved
    if (!this._currentShownBounds.equals(newBounds)) {
        this._topClusterLevel._recursivelyRemoveChildrenFromMap(this._currentShownBounds, Math.floor(this._map.getMinZoom()), this._zoom, newBounds);
        this._topClusterLevel._recursivelyAddChildrenToMap(null, Math.round(this._map._zoom), newBounds);
        this._currentShownBounds = newBounds;
    }
};

Can you please provide a minimal reproducible example and/or a stack trace? I'm not seeing any fire('moveend') calls in the MarkerCluster code.
