Add registry-based prod promotion, separate from auto dev deploy

Dev keeps auto-deploying on every push to main, same as before, but now also publishes each build to git.jerodrigged.com's container registry tagged by short commit SHA (best-effort - never blocks the dev deploy if REGISTRY_TOKEN isn't set yet). Prod deploys only on an intentional `git push origin main:prod`, and only ever pulls a pre-built SHA-tagged image - it never rebuilds from source. This guarantees prod runs the exact artifact dev already validated, and makes promoting an untested commit fail loudly (pull of a nonexistent tag) instead of silently rebuilding something new. Needs new secrets before the prod path works: PROD_SSH_KEY, PROD_HOST, PROD_USER, REGISTRY_USER, REGISTRY_TOKEN. PROD_SSH_KEY/PROD_HOST/ REGISTRY_USER are already set; PROD_USER and REGISTRY_TOKEN still need Jerod's input.

+# already validated. See docker-compose.deploy.yml and CLAUDE.md.
