Pull request overview
This PR adds a new Microsoft Teams hosting integration package and extends the activity model, while also refactoring core hosting types for improved type safety and consistency.
Changes:
- Introduces
microsoft_agents.hosting.msteamswithTeamsAgentExtension, Teams-specific route namespaces (channels/teams/messages/task modules/etc.), and internal helpers. - Adds
ActivityTreatment/ActivityTreatmentTypesto the activity entity model. - Refactors core hosting type definitions and a few core behaviors (e.g.,
HandoffHandlerprotocol,TurnContext.send_activityreturn type,Authorizationconnection naming).

This pull request introduces several new features and improvements across the Microsoft Agents libraries, focusing on extensibility, type safety, and support for Microsoft Teams integration.
Key highlights:
