/**
 * Runs nauth-toolkit migrations automatically on startup (zero consumer burden).
 *
 * @remarks
 * This dynamically loads the database-specific adapter package and asks it to run its
 * own adapter-owned migrations into the provided `DataSource`.
 *
 * The adapter serializes the run behind a database-level lock (Postgres advisory lock /
 * MySQL named lock), so multiple instances booting in parallel — ECS tasks, Kubernetes
 * pods — cannot race on the same schema. See `config.migrations`.
 *
 * Set `config.migrations.autoRun = false` to skip this entirely and apply migrations
 * out-of-band (for example from a one-off release task).
