feat(iios-kernel-client): per-request header factory → 0.1.4

RestConfig.headers now accepts a function, invoked once per request, so a caller can
mint a FRESH context attestation (new single-use nonce) each call. A static header was
replay-rejected on the 2nd request of a multi-call operation. Published 0.1.4.
