Pull request overview
This PR updates the AzureAI .NET agent creation flow so that when GetAIAgentAsync is called with ChatClientAgentOptions.UseProvidedChatClientAsIs = true, the extension skips invocable-tool validation, enabling manual tool handling via custom IChatClient middleware.
Changes:
- Update
GetAIAgentAsyncto disablerequireInvocableToolsvalidation whenUseProvidedChatClientAsIsis enabled. - Add a unit test asserting no exception is thrown in this mode when server function tools exist but no matching invocable tools are provided.

| dotnet/src/Microsoft.Agents.AI.AzureAI/AzureAIProjectChatClientExtensions.cs | Gates requireInvocableTools based on UseProvidedChatClientAsIs for GetAIAgentAsync. |
| dotnet/tests/Microsoft.Agents.AI.AzureAI.UnitTests/AzureAIProjectChatClientExtensionsTests.cs | Adds test coverage for skipping tool validation when UseProvidedChatClientAsIs=true. |
UseProvidedChatClientAsIs is a non-nullable bool, so use ! operator instead of != true for clarity. Co-authored-by: Copilot <223556219+Copilot@users.noreply.github.com>
…microsoft#3855) Always match provided AIFunctions to server-side function definitions regardless of requireInvocableTools flag. Only throw when validation is required and no match is found. This ensures UseProvidedChatClientAsIs still preserves user-provided AIFunction tools instead of falling back to the broken ResponseToolAITool wrapper.
