Gameplan to get all derivation names from system closure

1. Do nix eval --raw github:DestinyofYeet/nix-config#nixosConfigurations.teapot.config.system.build.toplevel.drvPath to get the root derivation path Output: /nix/store/nwpzp5w668101ncjfcmrixgm3gy0lgi5-nixos-system-teapot-26.11.20260813.0e251e2.drv

2. Do nix-store --query -R /nix/store/nwpzp5w668101ncjfcmrixgm3gy0lgi5-nixos-system-teapot-26.11.20260813.0e251e2.drv Output:
