Subject: [PATCH] feat: Update-Hinweis beim App-Start
MIME-Version: 1.0
Content-Type: text/plain; charset=UTF-8
Content-Transfer-Encoding: 8bit

Ruft /static/downloads/version.txt vom konfigurierten Server ab und
vergleicht gegen kAppVersion. Bei Abweichung Hinweis-Banner auf HomeScreen
("Neue Version X verfügbar, installiert: Y"). Rein informativ, kein
Auto-Update (APK-Sideloading, kein Play-Store-Mechanismus verfügbar).
Fehler beim Check (offline, Server down) werden stillschweigend ignoriert.
v0.1.5+6.
