Agent Protocol over MoQ

This document specifies a Agent-to-Agent communication framework enabling structured, low-latency, and semantically rich communication between autonomous agents over the Media over QUIC (MoQ) protocol. It leverages MoQ's efficient media transport capabilities while introducing a new application-layer framing mechanism to support control signaling, session management, and large data fragmentation. The design supports both intra-domain and inter-domain deployment, with an emphasis on interoperability, extensibility, and minimal overhead.
