/**
 * Mongoose plugin to synchronize MongoDB collections with a MeiliSearch index.
 *
 * This plugin:
 *   - Validates the provided options.
 *   - Adds a `_meiliIndex` field to the schema to track indexing status.
 *   - Sets up a MeiliSearch client and creates an index if it doesn't already exist.
 *   - Loads class methods for syncing, searching, and managing documents in MeiliSearch.
 *   - Registers Mongoose hooks (post-save, post-update, post-remove, etc.) to maintain index consistency.
 *
 * @param schema - The Mongoose schema to which the plugin is applied.
 * @param options - Configuration options.
 * @param options.host - The MeiliSearch host.
 * @param options.apiKey - The MeiliSearch API key.
 * @param options.indexName - The name of the MeiliSearch index.
 * @param options.primaryKey - The primary key field for indexing.
 * @param options.syncBatchSize - Batch size for sync operations.
 * @param options.syncDelayMs - Delay between batches in milliseconds.
