Jordan Ritter 56e85dfd80 feat(showcase): add bin/railway Ruby tooling for Railway ops
Single-file Ruby (stdlib only) with 9 subcommands for Showcase
Railway operations: snapshot, restore, rollback, rollback-commit,
promote, pin, env-diff, resolve-digest, lint-prod.

- Production protection: --yes + typed 'production' confirmation
  (--non-interactive skips the prompt but still requires --yes).
- Uniform exit codes: 0 clean, 1 drift/findings, 2 error.
- GraphQL via backboard.railway.app with serviceInstanceDeployV2.
- GHCR digest resolution via Docker-Content-Digest header.
- Promote prechecks: service-set parity, critical env-key parity,
  custom-domain audit; REFUSE on parity miss, WARN on domain drift.
- Minitest suite (stdlib) covers CLI parsing, snapshot YAML
  roundtrip, GHCR digest decision tree, and production prompt.
- CI workflow showcase_lint_prod.yml runs lint-prod + tests on every
  PR that touches showcase/.
