jammi-cli 0.7.0

//! CLI integration tests for `jammi mutable`.
//!
//! Catalog state is redirected to a per-test `TempDir` via the
//! `JAMMI_ARTIFACT_DIR` env var. The shipped fixtures under
//! `tests/fixtures/cp9/` provide tenant-neutral schemas; tests reach for
//! `feature_schema.json` directly so a regression in either the fixture or
//! the CLI surfaces immediately.
