zad-cli 0.9.4

//! Tests for the offline surface of `zad discord discover` / `directory`:
//! loading the file, manually mapping entries, and watching the runtime
//! verbs (`send`, `read`, `join`, `leave`, `channels`) resolve names the
//! directory knows about. None of these tests hit the network — the
//! `discover` happy path needs a bot token and is exercised by hand.
