dumbgit v0.13.0

What's new

A clearer, steadier commit graph — the graph now models branch identity separately from its on-screen lane, producing topology that is easier to follow while keeping the multi-repository view compact.

• Branch colors remain stable as paths move between lanes and as more history loads.
• First-parent paths stay separate until their real parent commit, so merges no longer create misleading early junctions.
• Finished paths compact left promptly, while merge connectors reuse the correct target branch.
• Stashes have their own graph nodes and direct connections to their base commits; stash lanes now use the first locally available space without widening the whole graph.
• Commit descriptions share a stable graph boundary, with a tighter column in Workspace cards.
• Loading more history preserves the scroll container and visible position, updates only the log, and avoids shifting existing stash lanes or colors.
