## 🔧 Fixed Issues

### Issue 1: Backup Creation Error ✅ FIXED
**Problem**: `ZipArchive::close(): Can't open file: No such file or directory`

**Solution**: 
- Fixed directory creation in `UpdaterService.php`
- Added proper path checks before ZIP operations
- Ensured directories exist with `mkdir()` before operations

**Changes Made**:
```php
// Before: Used Storage facade (didn't create directories)
Storage::makeDirectory(self::BACKUP_PATH);

// After: Direct directory creation with checks
$backupDir = storage_path('app/' . self::BACKUP_PATH);
if (!is_dir($backupDir)) {
    mkdir($backupDir, 0755, true);
}
```

## 🎯 How It Works

### 1. **Upload Update Package**
- Admin uploads ZIP file
- System validates: file format, size, manifest
- Stores in `storage/app/updates/`
- Creates database record with status "pending"

### 2. **Install Update**
- Creates automatic backup first
- Extracts ZIP to temp directory
- Copies files to application
- Runs migrations (if any)
- Runs seeders (if specified)
- Updates version number
- Clears all caches
- Marks as "completed"

### 3. **Rollback Update**
- Extracts backup ZIP
- Restores files to previous state
- Restores database (if included)
- Clears caches
- Marks update as "rolled_back"

### 4. **Backup System**
- Creates ZIP with: app/, config/, database/, resources/, routes/, Modules/
- Includes database dump (MySQL/PostgreSQL/SQLite)
- Stores in `storage/app/backups/`
- Provides download capability
- Automatic cleanup (keeps last 10)
