/**
 * Creates an embedding facade.
 *
 * Sync factory, async methods — same pattern as `tool()` and `agent()`.
 *
 * - `embed()` applies `queryPrefix` (optimized for search queries)
 * - `embedMany()` applies `documentPrefix` (optimized for document indexing)
 * - `embedMany()` automatically batches large inputs to stay within API limits
 *
 * @example
 * ```ts
 * const embedder = embedding({
 *   documentPrefix: "search_document: ",  // for Nomic, E5, BGE models
 *   queryPrefix: "search_query: ",
 * });
 * const vector = await embedder.embed("some query");
 * const vectors = await embedder.embedMany(["doc1", "doc2"]);
 * ```
