autumn-cli 0.7.0

//! Integration tests for `autumn db create | drop | reset`.
//!
//! These tests require Docker (via testcontainers) and are marked `#[ignore]`
//! so they only run when explicitly requested with `-- --ignored`.
//!
//! Run with:
//!   cargo test -p autumn-cli --test db -- --ignored --nocapture
