Subject: [PATCH] iso-builds: Dateigroesse speichern und ausliefern
MIME-Version: 1.0
Content-Type: text/plain; charset=UTF-8
Content-Transfer-Encoding: 8bit

Neue Spalte size_bytes (Migration 0024, analog zu sha256/Migration 0023) -
wird direkt nach erfolgreichem Bau einmalig berechnet (output_path.stat().
st_size) und zusammen mit sha256 gespeichert, kein Neuberechnen bei jedem
Seitenaufruf noetig.

Nutzer-Feedback (01.09.2026, echter Hardware-Test): "Bitte nach ISO-Build
auch die Größe anzeigen lassen" - kundenplattform zeigt sie jetzt auf
/installationsmedium an (iso_build.size_bytes | filesizeformat).
