Feature: Ledger Reads, Builder Publishing, and Network Presets

[sephynox]

Summary

The node client could transmit blocks but not read the ledger back, and every client had to be constructed from a raw URL and network id. This adds the read surface (blocks, chains, history, ACLs, votes), a publish path that accepts a caller-composed block builder, and well-known network presets so a client is one call from a network name.
