Subject: [PATCH] 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
