## Summary
Temporarily simplifies the resize logic to only work on bottom right
corner and eliminates edge cases where corner resizing caused position
drift issues.
- Remove multi-corner resize handles in favor of bottom-right only
- Delete resizeMath.ts and its tests (no longer needed)
- Simplify useNodeResize to only handle bottom-right resize
- Remove position tracking from resize callback
