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

+
+Fontkitten is a font data library, focused on font file parsing and metadata extraction.
+
+- 22x smaller install size than `fontkit`
+- 3x smaller bundle size than `fontkit`
+- Drop-in replacement for the supported APIs
+- Built-in TypeScript types
+
+Based on the [`fontkit`](https://www.npmjs.com/package/fontkit) package, Fontkitten aims to offer a lighter weight alternative for projects that do not require the full feature set of `fontkit`.
+See [“Differences from Fontkit”](https://github.com/delucis/fontkitten/blob/main/DOCS.md#differences-from-fontkit) for full details of changed APIs.
