//! DIDComm wire types for VTC join-request submission.
//!
//! The corresponding REST endpoint is `POST /v1/join-requests`;
//! over DIDComm the message `type` field IS the Trust Task URL
//! (workspace convention) and the DIDComm authcrypt sender
//! authenticates the applicant DID — no separate holder-binding
//! signature is needed (the envelope already binds the sender).
