auto-claude: subtask-1-1 - Add focusedIndex state and arrow key navigation logic

- Added focusedIndex state to track keyboard focus
- Enhanced handleKeyDown to support ArrowDown, ArrowUp, Enter, and Escape keys
- Added visual focus indicator with orange ring (ring-2 ring-orange-500)
- Implemented aria-activedescendant for screen reader support
- Added unique IDs to language options for accessibility
- Reset focusedIndex when dropdown opens/closes
