 * Memory-internal accessor for the embeddings operations that stay off
 * `@vellumai/plugin-api` (the self-contained ops live there — see
 * `persistence/embeddings/plugin-facade.ts`).
 *
 * `embedWithBackend` keeps its `config` parameter — it is a primitive whose
 * vectors the caller stores alongside its own config-derived metadata (cache
 * keys, vector-size checks, Qdrant collection), so it must embed with the
 * caller's exact config snapshot rather than a re-read that could diverge from
 * that metadata mid-operation. It is loaded via dynamic `import()` inside the
 * wrapper so importing this module does not eagerly pull the embed graph
 * (`embedding-backend`), which would break intentional partial module mocks
 * in memory tests. `resolveQdrantUrl` is synchronous — its consumers are
 * memoized client getters — so it is imported statically.
