Add stylix with theme, font and image configuration.
Change all relevant (current) options to that nix evaluates without
error, not fully tested yet though.
Remove plasma manager and associated components.
Condensed some files - remove some standalone files for packages with
much smaller configuration now that they're not being manually themed.
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
