Configures Pantheon (LightDM + gala) for daily use on this ASUS TUF Gaming A15 (FA507NU), and drops everything that only existed to serve the previous Hyprland/Quickshell setup: - desktop.nix: services.desktopManager.pantheon instead of programs.hyprland + greetd; comfy laptop touchpad defaults. - drivers.nix: NVIDIA PRIME render offload between the AMD Radeon 680M (drives the panel) and the RTX 4050 Max-Q (offload-only), using this machine's real PCI bus IDs; asusd/supergfxd for ASUS-specific laptop control. - apps.nix / scripts.nix: removed Hyprland/Quickshell-only packages and scripts (kitty, rofi, quickshell, mako, hyprlock, hyprpaper/mpvpaper, the Quickshell theme-picker scripts, cursor/wallpaper/display helpers) — Pantheon ships its own Files/Terminal/Screenshot/ notifications/theming natively. Kept the DE-agnostic scripts (vault toggle, metadata stripping, brightness control, Wi-Fi hotspot, telemetry, weather). - theme.nix and default-apps.nix deleted entirely — Pantheon owns GTK/icon theming itself, no more live dconf/CSS generation pipeline needed. - Deleted hyprland/ and dotfiles/ (kitty, mako, quickshell, rofi). Verified with `nixos-rebuild build`. Co-Authored-By: Claude Sonnet 5 <noreply@anthropic.com> Claude-Session: https://claude.ai/code/session_01RpiovBQL6k5MTDMN3Ln9nL
