This pull request introduces several updates to the streaming response and typing indicator logic for Microsoft agents hosting. The main changes focus on improving channel detection for streaming, enhancing activity entity information, and refining error handling in the typing indicator loop.

Streaming channel detection and activity entity improvements:

• Updated channel detection logic in _set_defaults to compare Channels.ms_teams and Channels.direct_line against context.activity.channel_id.channel, improving reliability in identifying streaming channels. (streaming_response.py)
• Added stream_id to the Entity within create_activity, ensuring that activity entities include the stream identifier for better tracking. (streaming_response.py)

Typing indicator error handling:

• Removed unnecessary re-raising of asyncio.CancelledError in the _typing_loop method, resulting in cleaner cancellation handling and reduced error noise. (typing_indicator.py)
