* 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 AgentThread to AgentSession rename in unit tests
Update MockAgentWithName in AIAgentTests.cs and DelegatingAIAgentTests.cs
to use the renamed AgentSession class and corresponding methods:
- AgentThread -> AgentSession
- GetNewThreadAsync -> GetNewSessionAsync
- DeserializeThreadAsync -> DeserializeSessionAsync
- thread parameter -> session parameter
* Fix: Rename GetNewSessionAsync to CreateSessionAsync to match API changes
* Fix: Add SerializeSession override and remove async from DeserializeSessionAsync

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)
