One-shot migrate container runs drizzle-kit migrate against DATABASE_URL
and exits 0 before web boots. web service depends_on with condition
service_completed_successfully, so failed migrations block web startup
instead of serving 500s against a stale schema. Broker deliberately does
NOT depend on migrate - it tolerates DB-down gracefully per DEPLOY_SPEC
and should keep serving WS peers even during migration failures.
Also excludes apps/cli from docker build context (CLI ships to npm, not
containers) to sidestep zod spec drift in its package.json vs lockfile.
Known followup: migrate image is 3.27GB due to pnpm catalog: specifiers
forcing full-workspace resolution. pnpm deploy bundle trim is a P2.
