Fixed rendering artifact where duplicate bottom borders appeared when components dynamically shifted positions (e.g., Ctrl+C in agent clearing status container). Root cause: Container wasn't reporting as "changed" when cleared (0 children), causing differential renderer to skip re-rendering that area. Solution: Container now tracks previousChildCount and reports changed when child count changes, ensuring proper re-rendering when containers are cleared. - Added comprehensive test reproducing the layout shift artifact - Fixed Container to track and report child count changes - All tests pass including new layout shift artifact test
