//! Contract tests for `kanban_cli::CliApp`'s builder surface.
//!
//! These drive the public plug-in API that third-party backend crates will
//! consume: build a `CliApp`, optionally register custom backends, and
//! confirm that the resulting `StoreManager` can build stores for exactly
//! the factories that were registered.
