+1.  **Promotes Preview to Stable:** The workflow identifies the latest `preview` release and promotes it to `stable`. This becomes the new `latest` version on npm.
-- This will create a branch `release/vx.y.z-preview.n`
+2.  **Promotes Nightly to Preview:** The latest `nightly` release is then promoted to become the new `preview` version.
-- We will run evals and smoke testing against this branch and the npm package. For now this should be manual smoke testing, we don't have a dedicated matrix or specific detailed process. There is work coming soon to make this more formalized and automatic see https://github.com/google-gemini/gemini-cli/issues/3788
