[BREAKING] Obsoleting ReflectingExecutor in favor of source gen (#3380 )

* Initial working version with tests.

* Updates to validate class data once instead of for each handler method. Also updated Diagnostics Ids to format of MAFGENWF{NUM}

* Formatting and trying to fix generation project pack.

* Another atempt at getting the genrators project to build.

* More attempts to fix generator build and pack.

* Fixing file encodings.

* Initail round of cleanup.

* Trying to fix packing.

* Still trying to fix pipeline pack.

* Remove obsolescence markers, sample updates, and docs from generator branch.

This commit separates the generator core functionality from the
deprecation of ReflectingExecutor. The removed changes will be
re-added in a dependent branch (wf-obsolete-reflector).

* Mark ReflectingExecutor and IMessageHandler as obsolete.

This commit deprecates the reflection-based handler discovery approach
in favor of the new [MessageHandler] attribute with source generation.

Changes:
- Add [Obsolete] to ReflectingExecutor<T>, IMessageHandler<T>, IMessageHandler<T,R>
- Add #pragma to suppress warnings in internal reflection code
- Update Concurrent sample to use new [MessageHandler] pattern
- Add Directory.Build.props for samples to include generator
- Add documentation files explaining the migration

fix: Subworkflows do not work well with HostAsAgent (#3240 )

Subworkflows run into issues with Checkpointing and the Chat Protocol:

* The concurrency rework made subtle changes in behaviour that introduced a hang when using subworkflows with ChatProtocol and streaming execution.
* The ResetAsync() implementation in WorkflowHostExecutor was improperly resetting the joinContext - this was happening on restore checkpoint _after_ the join context was attached when
* Subworkflows cannot be used as the start node when hosted AsAgent due to inability to treat Catch-All as a Chat Protocol
* Subworkflow ownership issue when used in non-concurrent mode after finishing a run

Also fixes:
* When ChatMessages are output by executors that are not agents, there is no corresponding AgentResponseUpdate/AgentResponse event

Breaking Changes
* [BREAKING CHANGE] It is possible to provide the wrong RunId when resuming from CheckpointInfo (even though the data already exists on CheckpointInfo)

When hosted using .AsAgent(), Workflows were not exposing inner errors coming as Exceptions (through the WorkflowErrorEvent)

[BREAKING] refactor: Fix unintuitive binding of StreamAsync (#1930 )

In #1551 we added a mechanism to open a Streaming workflow run without providing any input. This caused unintuitive behaviour when passing a string as input without providing a runId, resulting in the input being misinterpreted as the runId and the workflow not executing.

As well, the name caused confusion about why the Workflow was not running when using the input-less StreamAsync (since the Workflow cannot run without any messages to drive its execution).

fix: .NET: Concurrency Support for Orchestrations (#1689 )

Concurrent run support was recently added to workflows, but Orchestrations did not fully update to support it. A few executors were missing Cross-Run Shareable annotations, and the ConcurrentEnd executor needed to be factory-instantiated.

This also ports the fix for #1613 from #1637, to avoid waiting on that PR.

fix: InMemoryCheckpointManager is not JSON serializable (#1639 )

Checkpointing is used by the WorkflowHostAgent to be able to support resume from a provided thread. When a CheckpointManager is not specified, we use the InMemoryCheckpointManager and serialize its state into the thread's Serialize()ed JsonElement.

At some point InMemoryCheckpointManager became not serializable, breaking this behaviour. This change restores serializability, and adds a test.

.NET: Fix handoff function naming (#1370 )

* Fix handoff function naming

We don't need the agent's name or a guid in the handoff name... we can just use simple numbering. There's a possibility that someone built an agent with a built-in function tool named "handoff_to_x"; if that turns out to be an issue, we could add back some longer bit of randomness.

* Update dotnet/src/Microsoft.Agents.AI.Workflows/Specialized/HandoffAgentExecutor.cs

refactor: [BREAKING] Remove generic Workflow<T> (#1551 )

fix: Update WorkflowHostAgent post Checkpointing implementation (#1498 )

WorkflowHostAgent was initially implemented before Checkpointing was available. This meant that in order to support resuming, the WorkflowHostAgent needed to keep the runs around, which broke it when stricter rules about concurrent sharing of workflows during execution were introduced.

This change updates the hosting logic to release the underlying StreamingRun when the RunStreamingAsync or RunAsync are invoked, in favour of keeping the checkpointing information in the WorkflowThread to enable resumption.
