Switch to the PC config layout: Plasma, Limine, shared configs/

Same modules and settings as nexoniarz-config-nixos; only hardware.nix
differs. Pantheon/LightDM -> Plasma 6/SDDM, systemd-boot -> Limine,
system.nix/drivers.nix split into focused modules, Firefox prefs and
fastfetch config in configs/.

Laptop hardware kept: AMD 680M + RTX 4050 PRIME offload (bus IDs
unchanged), NVIDIA suspend fix, asusd + supergfxd, tablet driver,
DualSense ERTM fix, laptop scripts (brightness, hotspot, telemetry,
weather). Dropped: GoPro v4l2loopback webcam, blueman.

-  `nvidia-offload <command>`)
-- **Laptop control:** `asusctl` (fan curves, keyboard backlight, battery
-  charge limit) + `supergfxctl` (dGPU power-state switching)
+- **GPU:** AMD Radeon 680M (iGPU, drives the panel) + NVIDIA RTX 4050 Max-Q
+  (PRIME render offload only; run things on it with `nvidia-offload <command>`)
+- **Laptop control:** asusctl (fans, keyboard backlight, charge limit) + supergfxctl (dGPU power state)
 
 ## Layout
 
-- `configuration.nix` — top-level imports
-- `hardware-configuration.nix` — generated by `nixos-generate-config`, don't
-  hand-edit
-- `modules/system.nix` — bootloader, networking, time, sound, hardening,
-  nix-ld
-- `modules/drivers.nix` — hybrid graphics (NVIDIA PRIME offload), ASUS
-  daemons, misc hardware (webcam loopback, tablet driver)
-- `modules/desktop.nix` — Pantheon desktop environment
-- `modules/users.nix` — user account, Steam, Firefox, Flatpak
-- `modules/apps.nix` — all installed packages
-- `modules/scripts.nix` + `modules/scripts/` — small custom CLI helpers
-  (encrypted vault toggle, metadata stripping, brightness control, Wi-Fi
-  hotspot, system telemetry, weather fetch)
