//! [`AgentRegistryPort`] — write side of the agent registry.
//!
//! The read side is [`AgentResolverPort`](super::AgentResolverPort):
//! use cases that need live handles go through the resolver. This port
//! exists so operator-facing RPCs (`RegisterAgent`, `UnregisterAgent`)
//! can mutate the registry without coupling to a concrete adapter.
//!
//! Kept segregated from the resolver per ISP: the deliberation use
//! case does not need write access, and an adapter may reasonably
//! implement read but not write (e.g. a cache in front of a static
//! config file).
