/**
 * Build a JUDO mask string from attributes and relations.
 *
 * The mask format wraps comma-separated entries in curly braces.
 * Plain attributes are listed by name, while relations include their
 * target attributes in nested braces.
 *
 * @example
 * // Attributes only
 * buildMaskString({ attributes: [{ name: "born" }, { name: "name" }] })
 * // => "{born,name}"
 *
 * @example
 * // Attributes + relations
 * buildMaskString({
 *   attributes: [{ name: "born" }, { name: "name" }],
 *   relations: [{ name: "messages", target: { attributes: [{ name: "message" }] } }],
 * })
 * // => "{born,name,messages{message}}"
 *
 * @example
 * // Empty produces "{}"
 * buildMaskString({ attributes: [] })
 * // => "{}"
