Move system/home/default.nix into system/default.nix,
system/home/desktop/default.nix into system/desktop.nix to reduce
unnecessary duplication. Moved everything in home/desktop up to home/
and adjusted paths accordingly. Moved wallpapers up to system/ since
it makes sense with where it's used.
Merge allowUnfreePredicate into single place again since it seems to
override rather than combine if used multiple times.
Install NoMachine on all machines again by default.
Add separate config files for waybar, fuzzel, mako
Enable gnome-keyring as secret-service, with seahorse for interface
Restructure desktop-related things into a desktop directory
Move home/ directory under system/ directory. Remove duplicated
machine-specific config files, now handled as one per host (excluding
hardware-configuration directory)
Move as much configuration as possible out of flake.nix and into more
appropriate files (e.g. system/default.nix)
Add a desktop.nix and laptop.nix for system, both will import
home/desktop.nix and home/laptop.nix respectively to reduce
duplication in machine-specific config files
Remove games and streaming directories, moved directly into Vanguard
config file
Remove home/personal.nix since it ended up being empty after changes
Remove old sway config since I haven't been maintaining it and this
refactor will definitely break it
