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

+/**
+ * Get the plain-text value of a node.
+ *
+ * ###### Algorithm
+ *
+ * *   if `tree` is a comment, returns its `value`
+ * *   if `tree` is a text, applies normal whitespace collapsing to its
+ *     `value`, as defined by the CSS Text spec
+ * *   if `tree` is a root or element, applies an algorithm similar to the
+ *     `innerText` getter as defined by HTML
+ *
+ * ###### Notes
+ *
+ * > 👉 **Note**: the algorithm acts as if `tree` is being rendered, and as if
+ * > we’re a CSS-supporting user agent, with scripting enabled.
+ *
+ * *   if `tree` is an element that is not displayed (such as a `head`), we’ll
+ *     still use the `innerText` algorithm instead of switching to `textContent`
+ * *   if descendants of `tree` are elements that are not displayed, they are
+ *     ignored
+ * *   CSS is not considered, except for the default user agent style sheet
+ * *   a line feed is collapsed instead of ignored in cases where Fullwidth, Wide,
+ *     or Halfwidth East Asian Width characters are used, the same goes for a case
+ *     with Chinese, Japanese, or Yi writing systems
+ * *   replaced elements (such as `audio`) are treated like non-replaced elements
+ *
+ * @param {Nodes} tree
+ *   Tree to turn into text.
+ * @param {Readonly<Options> | null | undefined} [options]
+ *   Configuration (optional).
+ * @returns {string}
+ *   Serialized `tree`.
