Document Durable Task Scheduler client integration for Azure Functions

[Copilot]

This updates Azure Functions docs to cover the new Durable Task Scheduler client package introduced upstream, including the public client/worker registration APIs and configuration model. It also links host-side DTS setup guidance to the new client-side wiring documentation.

• Client integration coverage (azure-functions-connect.mdx)

  • Added a new Durable Task Scheduler client integration section for Aspire.Microsoft.DurableTask.AzureManaged.
  • Documented the client/worker extension surface:
    • AddDurableTaskSchedulerWorker
    • AddKeyedDurableTaskSchedulerWorker
    • AddDurableTaskSchedulerClient
    • AddKeyedDurableTaskSchedulerClient
  • Added guidance on when to use this client integration vs AppHost resource modeling.
  • Included package install block and keyed registration examples.

• Configuration + operational behavior

  • Documented DurableTaskSchedulerSettings and supported config paths:
    • ConnectionStrings:{connectionName}
    • Aspire:Microsoft:DurableTask:AzureManaged
    • Aspire:Microsoft:DurableTask:AzureManaged:{name}
  • Covered DisableHealthChecks and DisableTracing behavior for health/telemetry control.

• End-to-end wiring + cross-link

  • Added a minimal AppHost + Program.cs flow showing AddDurableTaskScheduler(...) resource setup and client-side consumption.
  • Added a host-page cross-link from azure-functions-host.mdx DTS section to the new client integration section.

// Program.cs
builder.AddDurableTaskSchedulerWorker("taskhub", worker =>
{
    worker.AddTasks(tasks =>
    {
        tasks.AddOrchestrator<MyOrchestrator>();
        tasks.AddActivity<MyActivity>();
    });
});

// Client-only scenario:
builder.AddDurableTaskSchedulerClient("taskhub");
