Subject: refactor(composer): move Composer and Factory from mozart-core to
 mozart
MIME-Version: 1.0
Content-Type: text/plain; charset=UTF-8
Content-Transfer-Encoding: 8bit

Composer needs DownloadManager (from mozart-registry), but mozart-core
sits below mozart-registry in the dependency graph — adding the field
would create a dependency cycle. Moving Composer and create_composer to
the mozart CLI crate breaks the cycle and lets the root state container
hold a DownloadManager.
