Place home-manager config under home directory, move system config
under system directory.
Add hostname-specific entries under home directory to be consistent
with how system is configured, update flake accordingly
Loads of expressions were a single default.nix in a directory, instead
just make a single directory
Hyprland is the only directory of expressions left
Move a few things around to fit this a bit better
Add home/default.nix to defer "import all" from flake.nix
Remove work email from default account set up, add to work laptop
specifically and only
Clean up a few unused expressions
nvim repo has been converted to flake for easier inclusion but still
stand-alone for non-nix systems
Move tokyonight repo fetch to flake input to keep consistent and reduce
multiple fetch calls
Reduce complexity and in flake.nix and be more efficient in re-using
things
Removed some reduandant files in home/ and tidied up the structure
somewhat
Moved things from desktop, gui, etc... to top level
Changed env to shell, indiv shell expressions import relevant others
