* Fix RequestInfoEvent lost when resuming workflow from checkpoint
* Fix streaming run double disposal in tests and lockstep republishing before Started event is emitted.
* Fix bug to remove messages after sending to avoid losing messages on send failure.
* Fix declarative test harness
* fix: HandoffAgentExecutor does not output any reponse when non-streaming
* fix: Ensure Workflow outputs persisted in chat history when hosted AsAgent
* fix: Remove duplicate history entry creation and ad test
* test: Add streaming tests for AsAgent to smoke tests
* feat: Add output configurability to Handoffs
* Handle external input request and response conversion for workflow as agent scenario
* Remove unnecessary test comment
* Fix PR comments
* Updated to fix edge cases, and add more tests.
* Update pending requests to use typed properties instead of relying on StateBag. replying to PR feedback.
* Fixed external response de-dup and updated possible brittle test.
* Address PR comments on sending turn token for normal messages and handle contentId collision by source agent
* Remove unnecessary serialization element and address pr comment on intercepted outgoing requests
* Updated MEAI changes for UserInput request and response abstractions.
* refactor: Normalize Run/RunStreaming with AIAgent
* refactor: Clarify Session vs. Run -level concepts
* Rename RunId to SessionId to better match Run/Session terminology in AIAgent
* [BREAKING]: Will break existing checkpointed sessions in CosmosDb due to field rename
* refactor: Rename and simplify interface around getting typed data out of ExternalRequest/Response
* Also adds hints around using value types in PortableValue
* refactor: Rename AddFanInEdge to AddFanInBarrierEdge
This will prevent a breaking change later when we introduce a programmable FanIn edge, analogous to the FanOut edge's EdgeSelector.
The goal, in the long run is to support a number of different FanIn scenarios, with naive FanIn (no barrier) by default, similar to FanOut.
* refactor: AsAgent(this Workflow, ...) => AsAIAgent(...)
* misc - part1: SwitchBuilder internal

* [BREAKING] refactor: Decouple Checkpointing and Execution APIs
With this change, Checkpointing becomes an property of an IWorkflowExecutionEnvironment. This lets environments that are tightly-coupled to their CheckpointManager avoid needing to present APIs that would not work (e.g. taking in an InMemory CheckpointManager for Durable Tasks, for example)
