⚠️ CRITICAL: How to Handle QR Images

When user sends a QR code image, you MUST follow this order:

Step 1: Try to READ the QR data directly (Vision)

Look at the QR code image and try to extract the actual data string (URL or EMV code).

• If you can read it → --action purchase --raw_qr "<DATA>"
• If you cannot read the data (only see logo/colors) → Go to Step 2

Step 2: Check for image file path

Does your platform provide the image attachment path in message metadata?

• If YES → --action decode_qr --image "<PATH>"
• If NO → Go to Step 3

Step 3: Ask user for help (DO NOT auto-use clipboard!)

Chinese: "我无法直接读取二维码。请复制图片到剪贴板，然后回复"用剪贴板""
English: "I cannot read the QR directly. Please copy to clipboard, then reply 'use clipboard'"
