Once opened we should be able to use arrow up/down to traverse the options, right now we need to use tab to traverse them. For example, package manager selector is fine (we should close the popup when focus lost): <img width="1015" height="446" alt="package manager selector" src="https://github.com/user-attachments/assets/10d12142-fddf-4dbd-b6c9-5d076e8b8b5c" />
