Customer buys a digital product.
The plugin generates a license key in the form shondalai-{uuid-v4} and stores it in #__easycommerce_licenses.
Customer signs in and opens My Account to view licenses and downloads.
Customer installs the extension on a site. The extension calls the activation endpoint and a row is written to #__easycommerce_license_activations.
Joomla checks the update server. The plugin validates the license, auto-activates the calling domain if needed, and returns the update XML with a signed download URL.
The customer's Joomla downloads and installs the new version.
