* 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)
* refactor: Normalize IsCheckpointingEnabled naming
* Updates to async run loop.
* fix: Workflow Onwership can be release by nonowner
* fix: Incorrect handling of blockOnPending in StreamingRun
Depending on whether we are running in streaming on non-streaming mode, we may be using the StreamingRun in different ways. Unfortunately, the only place we can really know what is the actual state of execution is in the RunEventStream implementations.
This resulted in blocking where blocking was unneeded and occasionally not-blocking when blocking was needed.
The fix is to move the logic of handling this blocking into RunEventStream implementations.
* fix: Fix cleanup on error and end run
This ensures we clean up the background resources correctly.
* fix: Ensure we let the run loop proceed when shutting down
* fix: Add timeout for Input Waiting
* fix: Make the samples properly clean up `Run`s and `StreamingRun`s
* fix: Simplify Declarative Workflow Run disposal pattern
* Also fixes missing .Disposal() in Integration tests

* feat: Add support for Workflow-as-Executor
* Fixes routing of 'object' compile-typed variables to properly take in type information
* Fixes a concurrency issue in StepTracer
* fix: Make Subworkflow ExternalRequests work properly
* fix: Threading and Concurrency fixes; prep for OffThread Mode
* refactor: Remove dead code around OffStreamRunEventStream
Currently not used, and will be replaced with a rewrite when brought back, so having it in the change is not valuable.
* ci: Work around issues with dotnet-format not properly analyzing the source
* fix: Fix the logic of AsyncCoordinator and AsyncBarrier
* Prevent individual wait cancellations from canceling the entire barrier
* Propagate information about whether the wait was completed or cancelled, and whether any waiters were present when released
* fix: Remove superfluous acces to .Keys in InProcStepTracer
* refactor: Clean up AsyncCoordinator's use of AsyncBarrier
