Adds --headless (or SAUSAGE_HEADLESS=1): console end of input does not stop the world; it runs until SIGTERM/SIGINT (stops actors, exit 0) or the broker exit message (exit 75, the loop's restart code). Pass it through the loop with nix run .#loop -- --headless <world>.

Seed: the repo has no seed folder. I read it as how fresh worlds get their docs: cli/src/lib.rs embeds PROTOCOL.md and writes it into every world at startup, so the headless documentation reaches new worlds that way. No unit generation was added.
