/**
 * Calculates the ending boundary index for virtualized content rendering.
 *
 * This function finds the last item that should be included in the viewport for
 * efficient virtualized rendering. It uses binary search to locate the last visible
 * position based on scroll offset and available space, then adds overscan items
 * to reduce flickering during scrolling.
 *
 * The function ensures we don't render beyond available data by clamping the result
 * to the maximum allowed count. The +1 adjustment makes the range inclusive since
 * binary search identifies the position just at the edge of visibility.
