gaming: move home module to gaming/ dir, add moonlight client toggle

Mirror the hosts/common/features/gaming/ layout on the home side: turn the single gaming.nix into a gaming/ directory. Moonlight (the client counterpart to the Sunshine host) becomes moonlight.nix, gated by its own custom.gaming.moonlight option so a host can install just the streaming client without the full launcher/Proton toolkit (custom.gaming.enable). - gaming.nix -> gaming/default.nix (imports moonlight.nix) - gaming/moonlight.nix: custom.gaming.moonlight -> moonlight-qt - arrakis: import gaming module, set custom.gaming.moonlight = true (replaces the one-off home.packages line) - konishi: update import path to the directory Co-Authored-By: Claude Opus 4.8 (1M context) <noreply@anthropic.com>
