//! DID-template management methods on [`VtaClient`] (global + context scope).
//!
//! **Transport model.** On the REST transport these hit the dedicated
//! `/did-templates` (and `/contexts/{id}/did-templates`) routes. On the
//! DIDComm transport there is no raw protocol surface — the VTA exposes
//! template management only through its Trust-Task dispatcher, so the DIDComm
//! leg dispatches the `trusttasks.org/spec/vta/did-templates/*` (and
//! `.../contexts/did-templates/*`) Trust Tasks via the binding envelope. Both
//! legs are wired through [`VtaClient::rpc_tt`] / [`VtaClient::rpc_tt_void`].
