magi-cli 0.109.0

//! The chat approval gate, through the real `magi answer` binary.
//!
//! `consult::validate_answer` is unit-tested directly, but the gate only takes
//! effect inside `answer_cmd`'s `agent_env()` branch. These tests spawn the
//! binary with `MAGI_RUN` / `MAGI_NODE` set the way an agent seat gets them, so
//! dropping the env lookup, the node check, the `--quote` hand-over or the
//! validate call fails here and not only in review.
