ia: Umbenennung — Library→Archiv, Wiki→Library (URLs, Content, Code)

Neue Informationsarchitektur:
- ARCHIV (/archiv) = die fertigen Texte (vormals Library): Essays mit Byline,
  Quellen/Zitieren, Dialog, Versionsverlauf. Section "archiv".
- LIBRARY (/library) = das verlinkte Werkstattwissen (vormals Wiki): zwei-
  spaltig mit Gruppen-Navigation + Filter. Section "library".

Umgesetzt:
- content/ + layouts/ verschoben (git mv), Menü (ARCHIV+LIBRARY, kein WIKI),
  Startseiten-Journal zieht jetzt Section "archiv", Querverweise umgeschrieben
  (/library→/archiv, /wiki→/library).
- CMS: files.js klassifiziert archiv/<sec>→beitrag, library/→biblio;
  stats.js + Admin (Typ "Library-Seite", KIND_LABEL, Pfade) nachgezogen.
- single.html: Byline/Provenance/Dialog an Section "archiv" gebunden.
- Beide Header zentriert (section-header) — einheitlicher Look.
- Interne Dialog-Werte (thread.kind='library', Forum "Beiträge") unverändert.
