InstantMessage class abstract interface

Interface for plaintext instant messages (unencrypted, first stage).

Represents the original, unencrypted message with plaintext content. This is the starting point of the message transformation workflow before encryption and signing.

Serialized format (Map/JSON):

{
  // Envelope metadata
  "sender": "moki@xxx",    // Sender's unique ID
  "receiver": "hulk@yyy",  // Receiver's unique ID
  "time": 123.45,          // Message timestamp (Unix timestamp in seconds)

  // Plaintext content (complete Content object)
  "content": {             // Unencrypted message body
    "type": "0",           // Content type
    "sn": 12345,           // Serial number (message ID)
    "text": "Hello World"  // Message-specific fields
  }
}
