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

+**Documentation: https://encoding.oslojs.dev**
+
+A JavaScript library for encoding and decoding data with hexadecimal, base32, base64, and base64url encoding schemes based on [RFC 4648](https://datatracker.ietf.org/doc/html/rfc4648). Implementations may be stricter than most to follow the RFC as close as possible.
+
+- Runtime-agnostic
+- No third-party dependencies
+- Fully typed
+
+```ts
+import { encodeBase64, decodeBase64 } from "@oslojs/encoding";
+
+const data: Uint8Array = new TextEncoder().encode("hello world");
+const encoded = encodeBase64(data);
+const decoded = decodeBase64(encoded);
+```
+
+## Installation
+
+```
+npm i @oslojs/encoding
