feat(system): add desktop preset module

Mirror of the laptop preset for the desktop form factor. New
`nomarchy.system.desktop.enable` defaults to `formFactor == "desktop"`,
so the installer's existing formFactor write auto-flips it on without
installer changes (same pattern as laptop).

The module pins `powerManagement.cpuFreqGovernor` to `"performance"`
(via mkDefault) and enables `services.zfs.{autoScrub,trim}` so a
future ZFS pool gets sensible maintenance for free. The ZFS knobs are
no-ops until the user adds zfs to `boot.supportedFilesystems`.

Battery widget filtering is already driven by `formFactor` itself in
`features/desktop/waybar/default.nix`, so the preset doesn't repeat
it. Closes the "Desktop preset module" Next item.

### `nomarchy.system.desktop.enable`
`bool`, default `nomarchy.system.formFactor == "desktop"`. Desktop preset: pins `powerManagement.cpuFreqGovernor` to `"performance"` (via `mkDefault`) and enables `services.zfs.autoScrub` + `services.zfs.trim` so a future ZFS pool gets sensible maintenance without further config. The ZFS knobs are no-ops until you add `boot.supportedFilesystems = [ "zfs" ]` (plus `networking.hostId`) and a pool. Battery-widget filtering is handled by `formFactor` itself, so this preset doesn't repeat it.
### `nomarchy.system.containers.enable`
`bool`, default `false`. Rootless Podman with Docker compatibility (`docker``podman`), plus `podman-compose`, `podman-tui`, and `dive`.

### Next (bigger lifts that build on Now)
- **Desktop preset module.** CPU governor `performance` by default, no battery widget (already done), ZFS-friendly defaults for users who later add a pool.
- **Accessibility preset.** Larger cursor, slower key-repeat defaults, `services.orca`, screen reader keybinding, high-contrast theme variant.
- **Gaming preset.** `programs.steam.enable`, `programs.gamemode.enable`, `services.flatpak.enable` with a curated remote, and a Hyprland window-rule to fullscreen Steam-launched apps.
- **First-run welcome wizard.** Extend `nomarchy-welcome` from a one-shot greeter into a guided picker: theme, panel position, monospace font, "what's a sane home.nix to start with?". Runs once, persists "done" in `state.json`.

- _2026-04-26_ — Desktop preset module (`core/system/desktop.nix`). New `nomarchy.system.desktop.enable` option; defaults to `formFactor == "desktop"` (mirror of the laptop preset's auto-enable). Pins `powerManagement.cpuFreqGovernor` to `"performance"` and enables `services.zfs.{autoScrub,trim}` so a future ZFS pool gets sensible maintenance for free.

Wires TLP (governors + 75/80 charge thresholds), force-disables `power-profiles-daemon`, enables `upower` and `thermald` (x86_64), adds the brightnessctl udev rule for backlight without root, and sets a logind lid-switch policy that defers to `hibernation.enable`. Closes both the Now item and the largest Next item.
