//! `heddle agent` — agent-loop affordances.
//!
//! `agent serve` runs a local-only gRPC daemon
//! over a Unix-domain socket inside the repo's `.heddle/sockets/`. The
//! daemon hosts agent services (state-review, discussion, signal,
//! operation-log query, transaction, hook) so a tight agent loop avoids
//! per-command process startup latency.
//!
//! `heddle agent serve` is intentionally distinct from `heddle daemon`,
//! which controls the FUSE mount daemon — different subsystem, different
//! UX. `heddle help daemon` contrasts the two.
