Subject: [PATCH 15/36] flake: add hosts

This will allow other modules to cross-reference which hosts exist on
which system.

My main use-case is to automatically declare home-manager configuration
for the home configuration of NixOS hosts.

I also include Darwin in case I ever want to use that in the future,
though that is unlikely for the moment.

WIP: this does not take into account the `profiles` which *also* setup
home-manager modules...

And here is what the last few commits were building up to.

This is neat, but won't be useful *very* often.

Subject: [PATCH 30/36] common: profiles: forward profiles to home-manager

We can only do this now that every profile has been migrated, otherwise
we would get errors about undeclared modules... It's not perfect, but
it's good enough.

This is only done for `type == "nixos"` for now, as I don't have any
Darwin configurations...

Subject: [PATCH 32/36] flake: add hosts

This will allow other modules to cross-reference which hosts exist on
which system.

My main use-case is to automatically declare home-manager configuration
for the home configuration of NixOS hosts.

I also include Darwin in case I ever want to use that in the future,
though that is unlikely for the moment.

This is neat, but won't be useful *very* often.
