Remove hardcoded nomad-addr input — NOMAD_ADDR is now injected by the
Forgejo runner via container.options using host.docker.internal.
Switch Nomad Variable path from static-sites/s3 to nomad/jobs so all
jobs in the namespace can read it without explicit ACL policies.

Use nix eval --raw --impure + builtins.getEnv instead of Python for
Nomad job JSON generation. Add flake-output input (default: default)
so projects can build non-default outputs like docs.
