- Add self.overlays.default to node01/02/03 configurations
- Makes service packages (chainfire-server, flaredb-server, etc.) available to NixOS modules
- Fixes "chainfire-server package not found" error during nixos-anywhere deployment
Root cause: NixOS modules reference pkgs.chainfire-server but packages were not in pkgs scope
Solution: Apply overlay that injects flake packages into nixpkgs
