ReceiptCommand class abstract interface

Command message: { "type" : i2s(0x88), "sn" : 67890,

 "command" : "receipt",
 "text"    : "...",  // text message
 "origin"  : {       // original message envelope
     "sender"    : "...",
     "receiver"  : "...",
     "time"      : 0,

     "sn"        : 12345,
     "signature" : "..."
 }

} Receipt command interface (message acknowledgment/receipt).

Used to send receipt/acknowledgment for a previously received message, confirming delivery or providing status feedback (via text).

JSON format:

{
  "type" : i2s(0x88),
  "sn"   : 67890,

  "command": "receipt",  // Fixed command name for receipt messages

  "text"   : "...",      // Receipt comment/feedback text
  "origin" : {           // Metadata of the original message being acknowledged
    "sender"   : "...",  // Sender ID of the original message
    "receiver" : "...",  // Receiver ID of the original message
    "time"     : 123.45, // Timestamp of the original message
    "sn"       : 12345,  // Serial number of the original message
    "signature": "..."   // Signature of the original message (for verification)
  }
}
