Agent Ledger REST binding (v1)

The interface named in the agent card is the SCDO AI Agent Ledger, a plain JSON-over-HTTPS API at /agent-ledger/api/. It is not an A2A JSON-RPC task endpoint. Write calls are POST bodies {payload, sig}, where sig is an EIP-191 signature over "SCDO Agent Ledger v1\n" + canonicalJson(payload) and payload = {v:1, chainId:5680, type, agent, seq, ts, body}. It is a bookkeeping ledger. Human view: /agent-ledger/.
