Adds a 'migrator' Dockerfile stage + Compose service that runs 'dotnet ef database update' once on bring-up, so a fresh SQL volume gets the schema with no operator step (quirk 1). cluster-seed + every host node depend on it via service_completed_successfully, so the seed never races an in-progress migration (quirk 2). Host build pinned to target: runtime (the migrator is now the last stage). entrypoint + README updated; the manual 'dotnet ef' first-time step is gone. Verified: down -v + up --build self-bootstraps (migrator+seed exit 0, 6 nodes up), deploy Sealed 6/6.

# `service_completed_successfully` — so by the time we run, migrations are fully

# applied. The dbo.ServerCluster wait below is therefore just a fast sanity check.
|
|
# Re-runs are safe: every insert in seed-clusters.sql is IF NOT EXISTS-guarded.
