- Move GUI applications from users/jsutter.nix to appropriate desktop modules: * office.nix: slack, signal-desktop * gaming.nix: discord, stremio * plasma.nix: arc-theme, pinentry, tigervnc * dev.nix: putty * media.nix (new): vlc, deluge - Create systems/common-headless.nix for server configurations: * Remove GUI dependencies (Flatpak, XDG portals, fonts, graphics drivers) * Include only essential CLI tools and server packages * Disable X server completely - Simplify skip01 configuration: * Remove Intel graphics drivers and OpenGL support * Use headless common configuration * Keep unified users/jsutter.nix (no split files) - Update flake.nix to include new media.nix module in desktop systems Result: Clean separation between desktop and headless configurations with improved modularity and maintainability.
