- Branch/tag tap opens one screen with swipeable Files/History tabs (Route.BranchDetail replaces Route.CodeBrowser/Route.History)
- Repository rows show last-commit time; repository All/Favorites tabs are swipeable
- Fix overlapping commit-detail layout (BoxWithConstraints sibling stacking)
- Fix BranchDetailScreen tab row jammed against status bar
- Fix diff view horizontal scroll not working
- Simplify references-loading message; remove in-app back buttons in favor of system back gesture; replace manual refresh buttons with pull-to-refresh
