BlogNav.astro: About-Eintrag in #submenu hinzugefügt. off-Logik der
Blog- und About-Sektion basiert jetzt auf den Hugo-Template-Quellen
(frontend-Branch):
- blogSectionOff = onAbout (aus tree.html: section-index blendet andere Sections aus)
- aboutOff = blogSelected (aus blog.html: alle Non-Blog-Sections immer off)
Auf Homepage und regulären Root-Seiten (Impressum, Datenschutz) sind
beide Sections sichtbar — wie in Hugo (Kind-/Geschwister-Logik).

about.html.astro, impressum.html.astro, datenschutz.html.astro:
menu-Slot mit BlogNav befüllt.
