//! Resolution of the orchestratectl root directory.
//!
//! Order: `$ORCHESTRATECTL_HOME` overrides everything, otherwise
//! `$HOME/.orchestratectl`. Used by every read/write subcommand so the
//! test harness can point at a `tempfile::TempDir` instead of the user's
//! real `~/.orchestratectl/`.
