Pull Request Overview

This PR addresses the scrolling behavior for the CarouselView on Android by updating how items changes are handled when the collection is modified, which in turn fixes the issue reported in #29415.

• Removed the conditional block that called UpdateAdapter() and ScrollToPosition() when Carousel.Loop was true
• Introduced unconditional calls to UpdateAdapter() and ScrollToPosition() in the add/remove item flow to ensure proper scroll updates

Comments suppressed due to low confidence (2)

src/Controls/src/Core/Handlers/Items/Android/MauiCarouselRecyclerView.cs:300

• The unconditional call to UpdateAdapter() now applies regardless of the Carousel.Loop setting. Please verify that this change produces the intended behavior for both looping and non-looping scenarios.

						UpdateAdapter();

src/Controls/src/Core/Handlers/Items/Android/MauiCarouselRecyclerView.cs:301

• With the removal of the conditional, ScrollToPosition(carouselPosition) is now called unconditionally. Please confirm that this is the desired behavior for accurately positioning the carousel when items are added or removed.

						ScrollToPosition(carouselPosition);
