Sausage agent

ci / check (push) Successful in 5s
- cli: the subcommand is optional; without one, sausage runs ./world and runs init first when ./world is not a world yet (test: cli/tests/cli.rs). So `nix run git+https://gitea.surma.technology/surma/sausage` works. - flake: .#loop without a folder runs bare sausage. - README: mention the bare command and the bare loop.
