### Composer Commands

```bash
# Install dependencies for production
composer install --no-dev

# Install all dependencies (including dev)
composer install

# Run tests (when implemented)
composer test

# Check coding standards
composer phpcs

# Fix coding standards automatically
composer phpcbf

# Lint PHP files
composer lint
```

### Running Tests

```bash
composer test
```

### Coding Standards

This plugin follows WordPress Coding Standards with PHP 7.4+ features including:
- Typed properties
- Arrow functions
- Null coalescing assignment
- Strict type declarations

## Using the New Architecture

### Example: Using the Lead Repository

```php
use InboundRocket\Database\Repository\LeadRepository;
use InboundRocket\Database\Models\Lead;

// Get repository from container (when implemented in your code)
$leadRepo = $container->make(LeadRepository::class);

// Find a lead by ID
$lead = $leadRepo->find(123);

// Find by hashkey
$lead = $leadRepo->findByHashkey('abc123');

// Search leads
$leads = $leadRepo->search('john@example.com');

// Get all leads with pagination
$leads = $leadRepo->getAll(limit: 20, offset: 0);

// Save a lead
$leadId = $leadRepo->save($lead);

// Delete a lead (soft delete)
$leadRepo->delete($leadId);
```

## Security
