Adds a complete Membership Layer to Subscriptions for WooCommerce (v2.0.0). Customers can now be granted time-bound memberships, either automatically from a subscription/order purchase or manually by an admin. Membership plans are managed as a custom post type, memberships are stored on user meta, and an Access Rules engine restricts content (posts, pages, products, Gutenberg blocks) to members of the right plan. Includes admin management UI, a My Account memberships tab, product badges/purchase CTAs, lifecycle emails, per-plan role assignment, and analytics — all covered by an extensive PHPUnit suite.
