Subject: [PATCH] chore(ci): add interim keep-alive cron for showcase starters
MIME-Version: 1.0
Content-Type: text/plain; charset=UTF-8
Content-Transfer-Encoding: 8bit

Adds a GitHub Actions workflow that curls /api/health on each of the
17 showcase starter services every 5 minutes to keep the agent's
in-memory state warm (JIT, module cache, connection pools). Railway
Pro tier doesn't sleep containers, but warm-state decays over idle.

Intentionally minimal: no Slack, no metrics, no state. Observability
is already covered by showcase_smoke-monitor.yml — this is strictly
keep-alive.

INTERIM — will be superseded by showcase-ops smoke probe cadence
once that service lands (see Notion proposal §2a).
