hyprpaper 0.8.0 was a full rewrite onto hyprtoolkit that dropped
preload= and the old wallpaper = monitor,path key=value line in
favor of a wallpaper { monitor = ... path = ... fit_mode = ... }
block (confirmed against hyprpaper's ConfigManager.cpp). The old
syntax silently matched nothing, so hyprpaper ran with zero wallpaper
settings and never displayed one — this was the actual cause of the
originally reported 'hyprpaper ignores my wallpaper' issue.
