//! SPDM Requester Service
//!
//! This service implements the SPDM requester (client) role, which initiates
//! attestation and measurement operations with SPDM responders.
//!
//! ## Overview
//!
//! The SPDM requester sends requests to responders to:
//! - Get version information
//! - Negotiate capabilities and algorithms
//! - Challenge the responder for attestation
//! - Retrieve measurements and certificates
//!
//! ## Architecture
