/**
 * BulkRelationalPlugin
 *
 * Adds relational/nested insert support to bulk mutations. When enabled
 * via `bulkRelational: true`, parent values item input types gain optional
 * fields for each "has many" relation, allowing creation of parent and
 * child rows in a single mutation.
 *
 * Example:
 *   mutation {
 *     bulkCreateCategories(input: {
 *       values: [{
 *         name: "Electronics"
 *         products: [
 *           { name: "Laptop", price: "999.99" }
 *         ]
 *       }]
 *     }) { affectedCount }
 *   }
 *
 * The FK column on the child table (e.g. category_id) is automatically
 * populated from the parent's returned primary key. Nested input types
 * exclude FK columns so the user does not need to provide them.
 *
 * Limitations:
 * - ON CONFLICT cannot be used with nested inserts (throws an error)
 * - Only one level of nesting is supported in the initial implementation
