feat: add gridview normalization to prevent redundant branch nodes
- Add normalize() method to Gridview class to eliminate single-child branch scenarios - Call normalize() in DockviewComponent.addGroup() to maintain clean structure - Implement safer disposal order to prevent potential memory leaks - Add cloneNode() helper function for proper node cloning during normalization Tests: - Add comprehensive test suite for normalize() method covering edge cases - Add integration test verifying addGroup() calls normalize() - Ensure normalization handles empty gridviews, single leafs, and multiple children correctly 🤖 Generated with [Claude Code](https://claude.ai/code) Co-Authored-By: Claude <noreply@anthropic.com>
