Dos primitivas reutilizables para apps web del registry: - random_hex_id_go_core: IDs hex aleatorios (apps con SQLite + IDs string) - spa_handler_go_infra: http.Handler que sirve embed.FS con fallback a index.html (patron SPA para React Router/dnd-kit) Ambas creadas via fn-constructor durante apps/kanban (issue 0053). Tests pasan, fn index OK. Co-Authored-By: Claude Opus 4.7 (1M context) <noreply@anthropic.com>
