//! TestRig -- a builder for wiring a real Agent with a replay LLM and test channel.
//!
//! Constructs a full `Agent` with real tools but a `TraceLlm` (or custom LLM)
//! and a `TestChannel`, runs the agent in a background tokio task, and provides
//! methods to inject messages, wait for responses, and inspect tool calls.

#![allow(dead_code)] // Public API consumed by later test modules (Task 4+).
