/**
 * graphile-llm — LLM Integration Plugin for PostGraphile v5
 *
 * Server-side text-to-vector embedding, text companion fields for pgvector
 * columns, and RAG (Retrieval-Augmented Generation) query support.
 *
 * Moves the embedding logic from the client (CLI --auto-embed) into the
 * Graphile server layer so clients work with text/prompts instead of raw
 * float vectors.
 *
 * @example
 * ```typescript
 * import { GraphileLlmPreset } from 'graphile-llm';
 *
 * const preset = {
 *   extends: [
 *     GraphileLlmPreset({
 *       defaultEmbedder: {
 *         provider: 'ollama',
 *         model: 'nomic-embed-text',
 *       },
 *       defaultChatCompleter: {
 *         provider: 'ollama',
 *         model: 'llama3',
 *       },
 *       enableRag: true,
 *     }),
 *   ],
 * };
 * ```
