Previously, unhandled exceptions from agent execution would bubble up
to the SDK orchestrator, which emits a generic 'An internal server
error occurred.' message — hiding the actual cause (e.g., 401 auth
failures, model not found, etc.).
Now AgentFrameworkResponseHandler catches non-cancellation exceptions
and emits a proper response.failed event containing the real error
message, making it visible to clients and in logs.
OperationCanceledException still propagates for proper cancellation
handling by the SDK.
Also bumps package version to 0.9.0-hosted.260403.2.

- InputConverter: stop propagating request.Model to ChatOptions.ModelId
Hosted agents use their own model; client-provided model values like
'hosted-agent' were being passed through and causing server errors.
- Add FoundryResponsesRepl sample: interactive CLI client that connects
to a Foundry Responses endpoint using ResponsesClient.AsAIAgent()
- Bump package version to 0.9.0-hosted.260403.1

Move source and test files from the standalone Hosting.AzureAIResponses project
into the Foundry package under a Hosting/ subfolder. This consolidates the
Foundry-specific hosting adapter into the main Foundry package.
- Source: Microsoft.Agents.AI.Foundry.Hosting namespace
- Tests: merged into Foundry.UnitTests/Hosting/
- Conditionally compiled for .NETCoreApp TFMs only (net8.0+)
- Deleted standalone Hosting.AzureAIResponses project and test project
- Updated sample and solution references

Implement Microsoft.Agents.AI.Hosting.AzureAIResponses to host agent-framework
AIAgents and workflows within Azure Foundry as hosted agents via the
Azure.AI.AgentServer.Responses SDK.
- AgentFrameworkResponseHandler: bridges ResponseHandler to AIAgent execution
- InputConverter: converts Responses API inputs/history to MEAI ChatMessage
- OutputConverter: converts agent response updates to SSE event stream
- ServiceCollectionExtensions: DI registration helpers
- 336 unit tests across net8.0/net9.0/net10.0 (112 per TFM)
- ResponseStreamValidator: SSE protocol validation tool for samples
- FoundryResponsesHosting sample app

* Add YieldOutputAsync calls to 05_WorkflowEvents sample executors
The integration test asserts that WorkflowOutputEvent is found in the
stream, but the sample executors only used AddEventAsync for custom
events and never called YieldOutputAsync. Since WorkflowOutputEvent is
only emitted via explicit YieldOutputAsync calls, the assertion would
fail. Added YieldOutputAsync to each executor to match the test
expectation and demonstrate the API in the sample.

* Fix GetExecutorName to handle agent names with underscores
Split on last underscore instead of first, and validate that the
suffix is a 32-char hex string (sanitized GUID) before stripping it.
This prevents truncation of agent names like 'my_agent' when the
executor ID is 'my_agent_<guid>'.

- DurableTask.Client.AzureManaged: 1.19.1 -> 1.22.0
- DurableTask.Worker: 1.19.1 -> 1.22.0
- DurableTask.Worker.AzureManaged: 1.19.1 -> 1.22.0

* Update Microsoft.Azure.Functions.Worker.Extensions.DurableTask to "1.16.0"
* Add the local.settings.json files to the sample which were previously ignored. This aligns with our other samples.
* Increase timeout for tests as CI has them failing transiently.
* increaset timeout value for azure functions integration tests.
* Add YieldsOutput(string) to workflow shared state sample executors
ValidateOrder and EnrichOrder call YieldOutputAsync with string messages,
but only their TOutput (OrderDetails) was in the allowed yield types.
This caused TargetInvocationException in the WorkflowSharedState sample
validation integration test.
* Downgrade the durable packages to 1.18.0
* Downgrading Worker.Extensions.DurableTask to 1.12.1
