This needs a bit of improvement. When the carousel reaches the end, instead of snapping back to the start, it should continue smoothly as an infinite scroll

@YashVerma24299 When can you update it? Issue #80 is blocked by this PR

[YashVerma24299]

Thanks for the suggestion.

I've updated the carousel to use a true infinite scrolling approach by duplicating items and animating based on the actual content width instead of percentages. This removes the snap-back effect and ensures a smooth, continuous loop.

Please let me know if this looks good now.

@YashVerma24299 It looks better than before, normal user won't notice it but there is just a slight jerk when the duplicate items come to the initial position. But it's okay for now
