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

+ * Text diff implementation.
+ *
+ * This library supports the following APIs:
+ * Diff.diffChars: Character by character diff
+ * Diff.diffWords: Word (as defined by \b regex) diff which ignores whitespace
+ * Diff.diffLines: Line based diff
+ *
+ * Diff.diffCss: Diff targeted at CSS content
+ *
+ * These methods are based on the implementation proposed in
+ * "An O(ND) Difference Algorithm and its Variations" (Myers, 1986).
