due to being on a wifi and my sim card not being able to do its job
properly this might have some errors
`nix flake check` gave me none for the current host but tbh who knows
this commit moves everything from `options` to `hosts/common` and
modifies the `createHost` function to import part of the files under
that directory by default
there's also a `hosts/common/optional` which is still being imported in
`profile.nix` but now in a better way using `lib.path.append` in tandem
with `lib.lists.map`
hopefully this will make it possible to have signed commits
previously I tried using the protonmail one but I can't assign that to
both the work and my personal account and I'm for sure not leaking my
work email
forgejo by default allows these fake emails so hopefully this works
