The commit history panel is now resizable with a draggable handle and keyboard support. The chosen width is persisted in local storage so the layout stays consistent across sessions. Git commit loading was also adjusted to include all branch tips for a more complete graph. - Add width persistence and pointer/keyboard resizing for history panel - Update commit graph query to use topo-order across all refs - Extend tests to ensure branch tips are included in commit results
