 * (block list, options form, icons) without a rebuild. Register them before
 * the editor mounts, e.g. in a Nuxt plugin.
 *
 * Blocks with an `ext__` bundle prefix (theme extensions) render through the
 * `extension_host` block component and share its icon.
 *
 * @example
 * ```ts
 * export default defineNuxtPlugin(() => {
 *   const { setRuntimeBlocks } = useBlokkliRuntimeBlocks()
 *   setRuntimeBlocks([
 *     {
 *       bundle: 'ext__acme__demo__usp_bar',
 *       options: {
 *         headline: { type: 'text', label: 'Headline', default: '' },
 *       },
 *     },
 *   ])
 * })
