SDK + X402 دفع هوك

1. SDK -> /openai/v1/chat/completions               (بدون Authorization)
   <- 402 Payment Required
      { accepts: [{ scheme:'upto', network:'eip155:8453', maxAmountRequired:'10000', ... }] }

2. داخل SDK -> paymentHandler({ url, method, body, accepts })   (توقيع محلي، 0 RTT)
   <- { headers: { 'PAYMENT-SIGNATURE': '<base64-envelope>' } }

3. SDK -> /openai/v1/chat/completions               (حقن رأس PAYMENT-SIGNATURE)
   <- 200 + استجابة العمل   (تمت التسوية على الخادم)
