// Tool: create_table
// Crea una tabla nueva delegando en /api/schema/create-table. Enviamos solo
// "intencion" (menuType + flags) — el server Python construye el schemaPreset
// por defecto. Los tableNames viajan SIN el prefijo `cms_`; la PK siempre es `num`.

Menu types:
 - 'multi': regular table with many records (news, products, contacts...)
 - 'single': single-record page (homepage, about us...)
 - 'category': category container — groups other tables under a menu node
 - 'separador': visual separator in the admin menu

Parameters:
 - tableName: technical name, lowercase + underscores, WITHOUT 'cms_' prefix. Primary key is always 'num'.
 - menuName: display name in the admin sidebar.
 - enlace: REQUIRED. Whether the table participates in public URLs (generates the 'enlace' field + slug). This is an architectural decision — ALWAYS ask the user before calling this tool.
 - seoMetas: adds SEO meta fields (title, description, og:image). Default false.
 - menuOrder: optional integer for sidebar order. Backend assigns one if omitted.`,
