/**
 * Returns a function that creates a document only if it does not already exist.
 *
 * Used by client-side accessor implementations (default, transaction) as their `create()` method.
 * Checks for document existence first, then calls `set()` if the document is absent.
 *
 * @param accessor - Accessor used to check for existence and write the new document.
 * @returns Create function that writes the document or throws when it already exists.
 * @throws {Error} When the document already exists at the reference path.
 *
 * @example
 * ```ts
 * const create = createWithAccessor(accessor);
 * await create({ name: 'New Item' }); // throws if document already exists
 * ```
