pin to nixos 26.05, drop hyprland/anyrun flakes

Stable restore point before 26.05 — last known good unstable config.

Unify all hosts on nixos-26.05 + home-manager release-26.05.
Drop hyprland, anyrun, nixpkgs-stable, home-manager-stable,
stylix-stable inputs. Hyprland 0.55.2 and anyrun 25.12.0 from
nixpkgs. Anyrun config via xdg.configFile (no HM module in 26.05).
Stylix on master until release-26.05 branch exists.
