Version 1.7.3: Fehlende Menü-Icons ergänzt

- MainWindow: Icons für drei bislang icon-lose Menü-Aktionen gesetzt
  - "Alle XML-Dateien transformieren" → play-circle
  - "Aus Datenbank laden" → database (neu)
  - "Worker-Pool-Metriken" → activity (neu)
- Zwei neue Feather-Icons (database, activity) ergänzt: Download-Skript,
  resources.qrc und resources_rc.py (via pyside6-rcc) aktualisiert

 Nachdem die Versionsdateien aktualisiert wurden (oder der Benutzer "Nein" gewählt hat), erstelle den Commit ganz normal nach den üblichen Commit-Konventionen. Falls die Version geändert wurde, füge die geänderten Versionsdateien zum Commit hinzu.
 
+### Schritt 4: Git-Tag setzen (nur bei Versionserhöhung)
+
+Wenn der Benutzer eine Versionserhöhung gewählt hat und der Commit erfolgreich war, setze einen annotated Git-Tag mit der neuen Version:
+
+```bash
+git tag -a "vX.Y.Z" -m "Version X.Y.Z"
+```
+
+Wobei `X.Y.Z` die neue Version aus `pyproject.toml` ist. Das Tag-Format ist immer `v` + Versionsnummer (z.B. `v1.7.1`).
+
+Informiere den Benutzer danach kurz: „Tag `vX.Y.Z` gesetzt. Mit `git push origin vX.Y.Z` kannst du ihn pushen."
+
+Wenn der Benutzer "Nein" gewählt hat, wird kein Tag gesetzt.
+
 ## Wichtige Hinweise
 
 - `pyproject.toml` **niemals direkt bearbeiten** — immer `uv version --bump` verwenden
