Read-Host has no tab-completion (that's a top-level PSReadLine feature,
not available to script prompts), so reuse the fzf dependency already
required for menus to browse folders interactively instead: navigate
into subfolders, go up with .., confirm current folder, or type a path
manually. Falls back to plain Read-Host when fzf isn't installed.
