Replace dev push builds with nightly schedule that only runs when dev head advances; still runs on manual dispatch. Plumb a ref input through reusable workflows so scheduled runs build the dev commit.
Switch dev workflow to publish the server under @neuralnomads/codenomad-dev with dist-tag latest, avoiding @dev dist-tags. Add workflow input to override package name at publish time.
Publish bleeding-edge builds from dev to GitHub prereleases and npm dist-tag 'dev'. Dev builds poll GitHub prereleases and surface update availability via /api/meta for UI notifications.
