Merge upstream/main into subtle-ux-improvements

Resolves conflicts and converts new defer/undefer commands from
fatih/color to the lipgloss semantic color system.

Key changes:
- Added StatusDeferred case in graph.go with ui.RenderAccent
- Converted status.go to use ui package for colorized output
- Converted defer.go/undefer.go to use ui package
- Merged GroupID and Aliases for status command
- Updated pre-commit hook version to 0.31.0
- Ran go mod tidy to remove fatih/color dependency
