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
