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

+ * Using a symbol or instanceof would not be able to recognize URL objects
+ * coming from other implementations (e.g. in Electron), so instead we are
+ * checking some well known properties for a lack of a better test.
+ *
+ * We use `href` and `protocol` as they are the only properties that are
+ * easy to retrieve and calculate due to the lazy nature of the getters.
+ *
+ * We check for auth attribute to distinguish legacy url instance with
+ * WHATWG URL instance.
+ *
+ * @param {unknown} fileUrlOrPath
+ *   File path or URL.
+ * @returns {fileUrlOrPath is URL}
+ *   Whether it’s a URL.
