Script Build Host migrations

Production schema changes run only through the numbered Alembic revisions in versions/. Runtime code must not invoke metadata.create_all(). CHECKSUMS.sha256 pins every applied revision; deployment verifies it before alembic upgrade and uses the revision's downgrade() for rollback. Tests may create the same metadata in a temporary SQLite database.
