### Workspace Management

```php
use Core\Mod\Tenant\Services\WorkspaceManager;
use Core\Mod\Tenant\Services\WorkspaceService;

// Get current workspace
$workspace = app(WorkspaceManager::class)->current();

// Create a new workspace
$workspace = app(WorkspaceService::class)->create([
    'name' => 'My Workspace',
    'owner_id' => $user->id,
]);
```

### Entitlements

```php
use Core\Mod\Tenant\Services\EntitlementService;

$entitlements = app(EntitlementService::class);

// Check if workspace has access to a feature
if ($entitlements->hasAccess($workspace, 'premium_feature')) {
    // Feature is enabled
}

// Check usage limits
$usage = $entitlements->getUsage($workspace, 'api_calls');
```

### Middleware

The module provides middleware for workspace-based access control:

```php
// In your routes
Route::middleware('workspace.permission:manage-users')->group(function () {
    // Routes requiring manage-users permission
});
```
