windowrulev2 deprecated in Hyprland 0.42+

[oameye]

Bug

/usr/share/hype/sddm/hyprland.conf line 23 uses windowrulev2 which was deprecated in Hyprland 0.42+:

windowrulev2 = workspace emptym,fullscreen, stayfocused, decorate 0, noanim, noborder, nodim, norounding, noshadow, class:^(sddm-greeter)$

This produces a config error at runtime on current Hyprland versions.

Fix

Replace windowrulev2 with windowrule — the syntax is otherwise identical:

windowrule = workspace emptym,fullscreen, stayfocused, decorate 0, noanim, noborder, nodim, norounding, noshadow, class:^(sddm-greeter)$

See the Hyprland wiki on window rules for details.
