Remove generic Astro/agent documentation files

These were boilerplate (starter README, AGENTS.md dev notes, CLAUDE.md
symlink) with no site-specific content.

-## 🚀 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                     |
