// These exercise the parts of the CLI that talk to a running server, spawn detached
// processes, and read/write the pid file. They rely on the `MOADIM_BIND_ADDR` and
// `MOADIM_HOME_OVERRIDE` seams to target an ephemeral port and a tempdir, and on the
// single-threaded test harness (`.cargo/config.toml`) so env mutation is race-free.
