v4.3.0 - Payment Intent Architecture

Added

• Payment Intent architecture - Checkout creates a payment intent via api.real8.org and redirects to app.real8.org/pay/{intent_id} for native wallet payment experience
• Smart landing page - PWA: shows payment dialog directly. Browser: shows "Open in REAL8 Wallet" + QR code
• Return URL handoff - After payment, wallet redirects back to store automatically
• Intent expiration - Payment links expire based on configured timeout
• HMAC authentication - Secured plugin-to-API communication
• Graceful fallback - Falls back to on-page payment instructions if API unreachable

Setup

1. Update the plugin
2. Go to WooCommerce > Settings > Payments > REAL8 Payments
3. Enter the Payment Intent Secret (same value configured on api.real8.org)
4. Save — checkout will now redirect to the REAL8 Wallet app
