Root cause: LicensingModule::init() was called from within
plugins_loaded but then tried to add ANOTHER plugins_loaded action
for LicenseManager::init(). Since plugins_loaded already fired,
LicenseManager::init() never ran and WooCommerce order hooks
were never registered.
Fix: Call self::maybe_init_manager() directly instead of
scheduling via add_action.
- Added woocommerce_payment_complete hook
- Added woocommerce_thankyou hook for COD/virtual orders
- Added is_virtual_order helper to detect virtual-only orders
- generate_licenses_for_order now called from multiple hooks
(safe due to license_exists_for_order_item check)
- LicensingSettings.php with key format, activation limits, expiry settings
- LicenseManager.php with key generation, activation/deactivation, validation
- LicensingModule.php with WooCommerce product meta integration
- LicensesController.php with admin, customer, and public API endpoints
- Database tables: woonoow_licenses, woonoow_license_activations
- has_settings enabled in ModuleRegistry
