refactor: synchronize focused menu index with refs for improved keyboard navigation

- Introduced a ref to keep the focused menu index in sync with state, enhancing keyboard navigation within the terminal context menu.
- Updated event handlers to utilize the ref for managing focus, ensuring consistent behavior during menu interactions.
- Simplified dependencies in the effect hook for better performance and clarity.
