/**
 * Nitro plugin that applies the Observational Memory migrations under its own
 * bookkeeping table. Mirrors `context-xray/plugin.ts`.
 *
 * NOT YET registered in the default plugin set — registering it means editing
 * shared bootstrap files (server/framework-request-handler.ts,
 * deploy/route-discovery.ts), which is deferred to the same follow-up that
 * wires `buildObservationalContext` into production-agent.ts. Until then the
 * store's `ensureTable()` creates the table lazily on first use, so OM is fully
 * functional without the plugin.
