feat(ci): auto-update updates.xml on production deploy

After a successful production deployment, the deploy workflow now
automatically updates updates.xml on main with the new version,
release URL, and docker image tag for the stable channel.

Dev deployments skip this step — only production releases update
the stable channel.
