- src/ui/components/cards.py: Changed WorkflowCard to use WorkflowRunModel with correct attributes
- src/models/__init__.py: Added WorkflowRunModel to exports
- src/ui/screens/dashboard.py: Fixed timer API for Textual 0.52 compatibility
- src/ui/components/loading.py: Renamed _animate to _spin for signature override
- src/git/status.py: Added type annotation 'str | None' to remote_name variable
