/**
* Flipping `signon.storage.rust.active` at runtime must switch the registered
* "passwords" engine between the legacy PasswordEngine and the Rust-backed
* RustPasswordEngine. The generic alternative machinery is covered by
* test_enginemanager.js; this guards the service.sys.mjs wiring against a
* key/name mismatch that would leave switchAlternatives() unable to swap the
* real engine.
*
* RustPasswordEngine.initialize() reaches into the active Rust store for its
* bridge, so getActiveStore() is stubbed to avoid depending on the Rust backend.
