onAppear doesn't fire during programmatic scrolling (UIScrollView contentOffset changes don't trigger SwiftUI lifecycle). Added onNearBottom callback to ScrollViewDriver — fires when within 500pt of bottom during auto-scroll tick. 3s cooldown prevents rapid-fire. Auto-scroll no longer stops at bottom — idles at maxOffset while loadMore fetches. When new entries arrive, contentSize grows and scrolling resumes automatically.
