.NET: Fix Error 404 Agent Hosted MCP (#3678 )

* Initial plan

* Fix issue #3195: Handle empty Version and ID in Azure AI agent responses

This fix addresses the issue where hosted MCP agents (like AgentWithHostedMCP)
fail with "ID cannot be null or empty (Parameter 'id')" error when deployed
to Azure AI Foundry.

Changes:
- Add CreateAgentReference helper method in AzureAIProjectChatClient that defaults
  empty version to "latest"
- Update CreateChatClientAgentOptions to generate a fallback ID from name and version
  when AgentVersion.Id is null or empty
- Add GetAgentVersionResponseJsonWithEmptyVersion and GetAgentResponseJsonWithEmptyVersion
  test data methods
- Add unit tests for empty version handling scenarios

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)

.NET: fix: Expose WorkflowErrorEvent as ErrorContent (#2762 )

* fix: Expose WorkflowErrorEvent as ErrorContent

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

The fix is to convert their message to an ErrorContent on the way out, rather than rely on the default "empty update" to collect the raw event.

* feat: Add a way to show/suppress exception information
