serve wire protocol

lasius serve — ndjson JSON-RPC over stdio, same wire as tamias serve / sepia serve / cuora serve / myco serve.

Framing

• Requests: one JSON object per line on stdin: {"op":"…", …}
• Responses: one JSON object per line on stdout: {"ok":true,"result":…} or {"ok":false,"error":"…"}
• Empty lines are ignored; the loop ends when stdin closes.

Ops

op	result
ping	{"pong": true}
list	{"repos": [names…], "count": n} — local clones under repos_dir
status	{"repos": [{name, branch, upstream, ahead, behind, dirty}…]}
doctor	{"checks": [{name, ok, detail}…]}

Unknown ops return ok:false with the expected-op list. Read-only by design — clone/update/rm print progress and would corrupt the protocol, so they stay CLI-side.
