docs+fix: improve README navigation docs and fix error state handling

- Add Vim-style navigation documentation in README
- Condense Lambda function details description for cleaner presentation
- Fix bug where error state would lock navigation, preventing back navigation
- Allow clearing errors with Enter key or back navigation
- Ensure proper state reset when navigating back from error screens

This improves user experience by documenting Vim-style navigation and
ensuring users can always navigate back from error states.
