v0.2.0

After-purchase WooCommerce verification mode: keep checkout low-barrier and verify on the order confirmation page, My Account order view, and order emails (issue #1). Guest verification via order key. Webhook receiver (HMAC-SHA256 + timestamp) so results land even if the browser is closed. Optional hold-until-approved and capped reminder emails (Action Scheduler). Sessions built server-side from order billing and reused. Verification status shown in the admin order screen. Update Didit Web SDK to 0.2.1.
