objectiveai-cli 2.1.2

//! `agents queue` — CLI-side dispatch for the queue subtree. `add`
//! is gone — `agents message` now handles enqueue under the hood.
//!
//! NOTE: scheduled for an upcoming refactor — the internal leaves
//! still reflect the prior shape and are intentionally left untouched
//! by the current rename pass.
