-//! The native `console` actor: your terminal.
-//!
-//! - `@<actor> <json>` sends a JSON body. `@<actor> <text>` sends
-//!   `{"type": "text", "text": ...}`.
-//! - A line without `@` goes to `agent` as text.
-//! - `/help`, `/quit`. EOF on stdin also quits (not with `--headless`, which
-//!   never reads stdin).
