Embed via serve

lasius serve reads one JSON request per line on stdin and writes one JSON response per line on stdout — the same ndjson wire as tamias serve, sepia serve, cuora serve, and myco serve.

printf '{"op":"list"}\n{"op":"status"}\n' | lasius serve

Ops: ping, list, status, doctor — read-only; mutating commands stay CLI-side so stdout stays protocol-clean. See the wire reference.
