Subject: [PATCH] gaming: declarative Flatpak via nix-flatpak (Bolt, Sober),
 Heroic + Proton-GE

Add nix-flatpak flake input and modules/gaming.nix managing Flatpak
remotes/packages declaratively: Bolt (Jagex launcher for RS3/OSRS) and
Sober (Roblox). Add Heroic and hyperplay-ext, plus Proton-GE for Steam.
Drops the old imperative runescape-launcher.
