feat(website): add marketing site aligned with v2.4.0 CLI

Adds the Astro-based website under website/ and a GitHub Pages
deploy workflow. Content is aligned with the current shipnode CLI:
TypeScript shipnode.config.ts (not .conf), full command surface
(backup, cloudflare, config, user, run, restart, stop, migrate,
upgrade), --config flag for multi-env deploys, and a project-local
install widget with npm/pnpm/yarn/bun tabs.

+# Astro Starter Kit: Minimal
+
+```sh
+npm create astro@latest -- --template minimal
+```
+
+> 🧑‍🚀 **Seasoned astronaut?** Delete this file. Have fun!
+
+## 🚀 Project Structure
+
+Inside of your Astro project, you'll see the following folders and files:
+
+```text
+/
+├── public/
+├── src/
+│   └── pages/
+│       └── index.astro
+└── package.json
+```
+
+Astro looks for `.astro` or `.md` files in the `src/pages/` directory. Each page is exposed as a route based on its file name.
+
+There's nothing special about `src/components/`, but that's where we like to put any Astro/React/Vue/Svelte/Preact components.
+
+Any static assets, like images, can be placed in the `public/` directory.
+
+## 🧞 Commands
+
+All commands are run from the root of the project, from a terminal:
+
+| Command                   | Action                                           |
+| :------------------------ | :----------------------------------------------- |
+| `npm install`             | Installs dependencies                            |
+| `npm run dev`             | Starts local dev server at `localhost:4321`      |
+| `npm run build`           | Build your production site to `./dist/`          |
+| `npm run preview`         | Preview your build locally, before deploying     |
+| `npm run astro ...`       | Run CLI commands like `astro add`, `astro check` |
+| `npm run astro -- --help` | Get help using the Astro CLI                     |
