//! meerkat-runtime — v9 runtime control-plane for Meerkat agent lifecycle.
//!
//! This crate implements the runtime/control-plane layer of the v9 Canonical
//! Lifecycle specification. It sits between surfaces (CLI, RPC, REST, MCP)
//! and core (`meerkat-core`), managing:
//!
//! - Input acceptance, validation, and queueing
//! - InputState lifecycle tracking
//! - Policy resolution (what to do with each input)
//! - Runtime state machine (Initializing ↔ Idle ↔ Attached ↔ Running ↔ Retired/Stopped/Destroyed)
//! - Retire/recycle/reset lifecycle operations
//! - RuntimeEvent observability
//!
//! Core-facing types (RunPrimitive, RunEvent, CoreExecutor, etc.) live in
//! `meerkat-core::lifecycle`. This crate contains everything else.
