Add the rule-46 image-publish lane: a `publish` job gated on
[lint, unit, integration] that builds the runtime Dockerfile in ci-builder
and pushes git.fabledsword.com/bvandeusen/steward:<sha> always, :dev on dev
and :latest on main. Authenticates with the REGISTRY_TOKEN repo secret
(the injected GITHUB_TOKEN lacks write:package). Steward is the first family
app to implement the publish lane; mechanics mirror CI-runner's
build-ci-python.yml.
Add compose.deploy.yml for a persistent remote instance that pulls :dev
(no source bind-mounts, persistent app_data+pgdata volumes, bundled Postgres),
plus a README "Remote dev instance" runbook and the POSTGRES_PASSWORD env key.
Fix .env.example's database URL var to the canonical STEWARD_DATABASE_URL
(single underscore) and document the publish lane in ci-requirements.md.
