- Implement useAutocomplete hook with fuzzy matching and Redis integration
- Add visual feedback showing up to 5 suggestions below input
- Support Tab key for completion with common prefix algorithm
- Real-time suggestion updates as user types
- Path normalization (handles ./, trailing slashes)
- Case-insensitive matching with scoring algorithm
- Add 21 unit tests with jsdom environment
- Update Input component with storage and projectRoot props
- Refactor key handlers to reduce complexity
- Install @testing-library/react, jsdom, @types/jsdom
- Update react-dom to 18.3.1 for compatibility
- Configure jsdom environment for TUI tests in vitest config
- Adjust coverage threshold for branches to 91.5%
- Fix deprecated ErrorChoice usage (use ErrorOption)
