Code Review
This pull request refactors geometry clearing logic in _RenderObjectSemantics by extracting helper methods _getExplicitSiblingChildren and _clearSubtreeGeometry, and adds a widget test to verify geometry updates on layout resize. The feedback suggests adding /// documentation to these new private methods in accordance with the Flutter Style Guide, and optimizing _getExplicitSiblingChildren using a sync* generator to avoid closures and temporary list allocations.

Does this mean we only clean explicit sibling children when the node doesn't form a semantics node?

explicit sibling children will form a node, we will be cleaning geometry of those node, but not the other.
For children that won't form a semantics node, their geometry is not used and won't get calculated. If at some point that child becomes explicit, its geometry will be cleared at that time
