Behavioral Notes

• Sending: A client should send this message when the user begins typing in the input field for a specific contact. To prevent network flooding, the client MUST rate-limit these messages (e.g., sending one only after a brief moment of continuous typing and waiting several seconds before sending another).
• Receiving: Upon receiving msgTyping, a client should display a "typing" indicator for the sender. This indicator should automatically hide after a short timeout (e.g., 5 seconds) to account for the sender pausing or closing the application without sending another notification.
• Reliability: The StreamMessage envelope for this message should set requireRcvConfirmation to false. It is a non-critical hint, and its loss is acceptable.
• Bot Interaction: This message is generally ignored if received from a bot address, as bots do not "type" in a conventional sense.
