Act as an Expert Next.js 14 and Technical SEO Specialist. Based on our production environment at "https://jobenapps.cloud", implement a complete SEO structure for our landing page using Next.js App Router Metadata API, reflecting our latest brand change to "MisiPintar".

Please generate and update the following files exactly with zero TypeScript errors:

1. Update or Create `src/app/layout.tsx`:
- Add a global `metadata` object of type `Metadata` from 'next'.
- Define the following metadata fields:
  * title: { default: "MisiPintar - Solusi Misi Edukatif & Literasi Keuangan Anak", template: "%s | MisiPintar" }
  * description: "Ubah kuota marah-marah menjadi kuota senyuman. Aplikasi manajemen tugas anak dan pembentukan karakter berbasis misi pintar untuk mendidik kedisiplinan sejak dini."
  * metadataBase: new URL("https://jobenapps.cloud")
  * openGraph: { title, description, url: "https://jobenapps.cloud", siteName: "MisiPintar", locale: "id_ID", type: "website" }
  * robots: { index: true, follow: true }

2. Create a dynamic robots file at `src/app/robots.ts`:
- Import `MetadataRoute` from 'next'.
- Export default function `robots()` that returns `MetadataRoute.Robots`.
- Configure rules:
  * Allow indexing for the public routes: `/`, `/register`, `/tentang-kami`, `/privasi`, and `/hubungi-kami`.
  * STRICTLY Disallow indexing for any internal dashboards by blocking `/dashboard`, `/dashboard/*`, and `/api/*` to protect user data and prevent duplicate content.
  * Point the sitemap URL directly to "https://jobenapps.cloud/sitemap.xml".

3. Create a dynamic sitemap file at `src/app/sitemap.ts`:
- Import `MetadataRoute` from 'next'.
- Export default function `sitemap()` that returns `MetadataRoute.Sitemap`.
- Return an array containing our updated public pages structure:
  * Route `/` (Landing Page) -> lastModified: new Date(), changeFrequency: 'daily', priority: 1.0
  * Route `/register` -> lastModified: new Date(), changeFrequency: 'weekly', priority: 0.8
  * Route `/tentang-kami` -> lastModified: new Date(), changeFrequency: 'monthly', priority: 0.7
  * Route `/privasi` -> lastModified: new Date(), changeFrequency: 'monthly', priority: 0.5
  * Route `/hubungi-kami` -> lastModified: new Date(), changeFrequency: 'monthly', priority: 0.7

Ensure all code follows the strict Next.js 14 standards, has proper TypeScript types, and compiles cleanly without errors in production mode.
