🚀 Add One-Button Interactive System Optimizer

✨ New Features:
- Interactive one-button optimizer with smart detection
- Analyzes existing optimizations and detects suboptimal configs
- User-controlled selective optimization (no forced changes)
- Handles mixed scenarios (some optimal, some suboptimal, some missing)
- Quick status checker for system overview
- Auto-sudo launcher for ease of use

🎯 Key Improvements:
- Detects when optimizations exist but aren't ideal (e.g., oversized zram)
- Only prompts for optimizations that need attention
- Leaves well-configured systems alone
- Clear status reporting and user choice
- German locale support for system commands

🔧 Components Added:
- one-button-optimizer.sh: Main interactive optimizer
- quick-status-check.sh: Quick system status overview
- launcher.sh: Auto-sudo convenience launcher
- Updated README with usage instructions

Tested on 15GB RAM system with mixed optimization state.

+## ✨ **NEW: One-Button Optimizer**
+
+🎯 **Quick Start:** `sudo ./one-button-optimizer.sh`
+
+The **one-button optimizer** is an intelligent, interactive system optimizer that:
+
+- 🔍 **Analyzes current optimizations** and detects suboptimal configurations
+- 🤔 **Prompts for user choice** on each optimization 
+- 🎯 **Applies only selected optimizations** - no forced changes
+- ✅ **Recognizes existing optimal configurations** and leaves them alone
+- ⚙️ **Handles mixed scenarios** where some optimizations exist but aren't ideal
+
+### Quick Tools
+
+- `./one-button-optimizer.sh` - **Main interactive optimizer** (recommended)
+- `./quick-status-check.sh` - **Quick system status** overview (no changes)
+- `./launcher.sh` - **Auto-sudo launcher** for the optimizer
+
 ## 🎯 Features
 
 - **Hardware Detection**: Automatically detects RAM, CPU, storage configuration
 - **Usage Analysis**: Identifies frequently accessed files and directories  
 - **Intelligent Tuning**: Applies optimizations based on system characteristics
+- **Interactive Mode**: User control over what gets optimized
+- **Suboptimal Detection**: Finds and offers to fix existing but suboptimal configs
 - **Modular Design**: Easy to customize and extend
 - **Safe Deployment**: Backup and rollback capabilities
 - **Multi-Distribution**: Works across different Linux distributions
