The @@ picker only listed files with no preview. It now lists both files and directories via fd (matching _fzf_search_directory), and shows a bat-highlighted or image-rendered preview through _fzf_preview_file. Image previews use a kitty-graphics-protocol, chafa, viu, timg fallback chain via the new _fzf_preview_image helper, benefiting the Ctrl+F directory search and git-status pickers as well since they share the same preview helper.
