Frontend uudelleenrakennettu: Astro-komponentit, Wasm pääsäikeessä, ei Workeria

Vanha frontend siirretty temp/. Uusi rakenne:
- StatusBar.astro, Terminal.astro, Editor.astro, Guide.astro
- global.css erillinen
- Wasm pääsäikeessä (ei Worker — yksinkertainen, debugattava)
- Tab-completion, dropdown, projektikortti, Monaco, GUIDE.md
- Ei tokenisointia eikä koodilaboratoriota

+
+Vite (French word for "fast", pronounced `/vit/`) is a new breed of frontend build tool that significantly improves the frontend development experience. It consists of two major parts:
+
+- A dev server that serves your source files over [native ES modules](https://developer.mozilla.org/en-US/docs/Web/JavaScript/Guide/Modules), with [rich built-in features](https://vite.dev/guide/features.html) and astonishingly fast [Hot Module Replacement (HMR)](https://vite.dev/guide/features.html#hot-module-replacement).
+
+- A [build command](https://vite.dev/guide/build.html) that bundles your code with [Rollup](https://rollupjs.org), pre-configured to output highly optimized static assets for production.
+
+In addition, Vite is highly extensible via its [Plugin API](https://vite.dev/guide/api-plugin.html) and [JavaScript API](https://vite.dev/guide/api-javascript.html) with full typing support.
