In-process HTTP test utilities for Minco and Axum applications.
`TestClient` calls an `axum::Router` directly as a Tower service, avoiding a
socket while exercising the real router and middleware stack. The crate also
captures deterministic command evidence for quality and deployment gates.
```rust
use axum::{Router, routing::get};
use http::StatusCode;
use minco_test::TestClient;
```
