Release v0.0.0.5

- Scan all stores recursively instead of only the default folder
- Properly release COM objects to avoid leaks
- Better error handling with debug output per store/folder
- Show error message if Outlook is not reachable
- Fallback to default contacts folder if recursive scan finds nothing

+### Release erstellen
+
+Das Release-Script automatisiert den kompletten Release-Prozess:
+Versionsnummer aktualisieren, bauen, Installer erstellen, Git Tag + Push
+und Gitea Release mit Setup-EXE als Download hochladen.
+
+```bash
+./release.sh <version> ["beschreibung"]
+```
+
+Beispiele:
+```bash
+# Release mit Standard-Beschreibung
+./release.sh 0.1.0.0
+
+# Release mit eigener Beschreibung
+./release.sh 0.2.0.0 "Neues Feature: Auto-Sync"
+```
+
+Das Script fragt beim Start nach Gitea-Benutzername und Kennwort
+und fuehrt dann folgende Schritte automatisch aus:
+
+1. Prueft Voraussetzungen (dotnet, docker, curl, sauberes git)
+2. Aktualisiert Versionsnummer in `.csproj`, `AboutForm.cs` und `setup.iss`
+3. Baut das Projekt (`dotnet build -c Release`)
+4. Erstellt den Installer via Docker (`amake/innosetup`)
+5. Git Commit + Tag (`vX.X.X.X`)
+6. Push zu Gitea (main + tag)
+7. Erstellt Gitea Release mit Setup-EXE als Download-Anhang
+
+Voraussetzungen:
+- .NET 8 SDK
+- Docker
+- curl
+- Gitea-Account mit Push-Rechten auf das Repository
+
