- detect::scan_games_in_prefix() walks drive_c/Program Files and
Program Files (x86) up to depth 4, skipping Windows system dirs,
the launcher's own exe, and already-configured games
- Empty game list now shows "No games added yet." with two actions:
· Scan for games — async scan of the Wine prefix, results appear
as a clickable list with + buttons to add each found exe
· Browse exe… — native file picker (zenity/kdialog) opening in
drive_c/, computes the relative path automatically
- Add-game form gains a Browse… button to pick exe from the prefix
- util::pick_file() added alongside pick_folder()
