Migrate git config to the settings option, fix the signing key path and email, add argo-rollouts/google-cloud-sdk and other tooling, enable go, and wire a dedicated nixpkgs-unstable input so claude-code tracks unstable independently of the pinned nixpkgs.
Enable rootful docker with Docker Desktop proxy patch, add emmathorpe to the docker group, disable resolvconf and enable nix-ld so the WSL distro behaves.
