• Feat: Add onReady, called after each initial placement and scroll cycle completes, including cycles restarted by a dataKey change.
• Fix: End-following and animated programmatic scrolling now stay aligned through footer, viewport, and native layout changes, while user dragging cancels queued follow requests.
• Fix: onStartReached and onEndReached callbacks now fire reliably after layout and dataset resets, including short lists and gestures that cross a threshold over multiple events.
• Fix: Numeric initialScrollIndex values that target the last row now include the footer when opening at the end.
• Perf: Fast scrolling now prepares rows in the direction you are moving, including upward and end-aligned scrolling, so the next content is ready sooner.
