* .NET: Add A2A input-request content for human-in-the-loop scenarios Adds first-class support for handling user input requests from A2A agents when they return an `input-required` task state. - Add `A2AInputRequestContent` (wraps the requested `AIContent`) and `A2AInputResponseContent` (wraps the user's `AIContent` reply), with `CreateResponse` helper overloads on the request type. - Surface input requests on `AgentResponse` / `AgentResponseUpdate` via `AgentTask` and `TaskStatusUpdateEvent` mappings. - Link follow-up messages containing `A2AInputResponseContent` to the existing task via `TaskId` instead of `ReferenceTaskIds`. - Add `A2AAgent_HumanInTheLoop` sample and register it in the solution and parent README. - Add unit tests for the new types, extensions, and `A2AAgent` paths.

Also adds tests for both RunAsync and RunStreamingAsync paths.

[]' fallback so Contents stays null when there are no input requests, matching the other update mapping patterns. Co-authored-by: Copilot <223556219+Copilot@users.noreply.github.com> * Use consistent GUID format for request IDs Use ToString("N") to match message ID format used elsewhere in the A2A component. Co-authored-by: Copilot <223556219+Copilot@users.noreply.github.com> * Remove Debug build exclusion for the HumanInTheLoop sample so it participates in normal solution validation. * Add missing using Microsoft.Extensions.AI to A2AAgent_HumanInTheLoop The sample uses ChatMessage, TextContent, and ChatRole types from Microsoft.Extensions.AI but was missing the using directive, causing CS0246 build errors on all CI jobs.
