• Added a dedicated License admin view for entering and managing the MAC Core license key.
• Added SureCart-powered licensing support for licensed manual update delivery.
• Added release metadata for the plugin distribution flow through the shipped release manifest.

• Kept the plugin row and admin access aligned with the license-management flow used by the project plugin stack.
