Add system/modules/desktop.nix (counterpart to laptop.nix): imports the
workstation base and uses wired NetworkManager instead of iwd.
Thread a `portable` flag (default true) through mkHost into specialArgs and
home-manager.extraSpecialArgs, mirroring username/fullName. lyrathorpe/home/
sway.nix consumes it to drop mobile components on desktop hosts:
- status bar swaps the battery block for CPU temperature + network throughput
- screen-brightness keybindings are omitted (no internal backlight)
No host uses desktop.nix yet; a future desktop host imports it and sets
`portable = false`. Verified by evaluating sway.nix both ways:
laptop -> [.. sound battery time] + brightness keys;
desktop -> [.. temperature net sound time], no brightness keys.
