Pull request overview
Adds “prompt preview” support so bots can reference an original targeted message by attaching a targetedMessageInfo entity (with the original message ID) to outgoing activities, enabling Teams to render a collapsible prompt preview.
Changes:
- Introduces
TargetedMessageInfoEntityto the API models and exports it via the entity model surface. - Auto-attaches
TargetedMessageInfoEntity(message_id=<incoming.id>)inActivityContext.send()when handling an inbound targeted message (unless already provided by the developer). - Adds unit tests and extends the targeted-messages example to demonstrate reactive and proactive usage.

Prompt preview allows a bot to reference the original targeted message in its reply, so Teams can render a collapsible preview of the user's prompt.
When a bot replies to a targeted message (reactive scenarios), the SDK now passes the original message's messageId via a targetedMessageInfo entity in the activity's entities array.
For proactive replies, developers can attach the entity themselves with the messageId of the targeted message.
