/**
 * @fileoverview chainweb_send - POST a pre-signed transaction after preflight.
 *
 * Security invariant: the server NEVER accepts private keys. The caller must
 * provide a `{cmd, hash, sigs}` tuple produced by their signing toolchain.
 * The server runs a local preflight and refuses to POST /send if the
 * preflight returns `status: "failure"`.
