Integrate Temporal .NET SDK into AdvancedSearch project

[devin-ai-integration]

Summary

Integrates the Temporal .NET SDK into the AspNetCore/React/AdvancedSearch project, wrapping the existing weather forecast generation in durable Temporal workflows.

Changes:

• Added Temporalio and Temporalio.Extensions.Hosting v1.5.0 NuGet packages
• Created Workflows/WeatherActivities.cs — Temporal activity that generates weather forecast data
• Created Workflows/WeatherWorkflow.cs — Temporal workflow that orchestrates the activity
• Updated Startup.cs — registered Temporal client (configurable via Temporal:TargetHost and Temporal:Namespace in appsettings) and a hosted worker on advanced-search-task-queue
• Updated SampleDataController.cs — WeatherForecasts endpoint now starts a Temporal workflow and awaits its result instead of generating data inline
• Added docker-compose.yml for running Temporal server + UI locally

The React frontend (FetchData.js) requires no changes — the API contract is unchanged.

Review & Testing Checklist for Human

• Verify the Temporal NuGet package versions (1.5.0) are compatible with the project's .NET 6.0 target framework
• Start Temporal server via docker-compose up in AspNetCore/React/AdvancedSearch/ before running the app
• Run the app and confirm api/SampleData/WeatherForecasts returns forecast data through the Temporal workflow
• Check the Temporal UI at http://localhost:8080 to verify workflows are executing on advanced-search-task-queue
• Confirm the EasyQuery middleware and other endpoints are unaffected

Recommended test plan:

1. cd AspNetCore/React/AdvancedSearch && docker-compose up -d
2. dotnet run
3. Navigate to the app and verify the weather forecasts page loads correctly
4. Open http://localhost:8080 to inspect completed workflows in the Temporal UI

Notes

• The WeatherForecast model has been moved from SampleDataController into WeatherActivities to be accessible by the workflow. The data shape is identical.
• Temporal host/namespace are configurable via appsettings.json under Temporal:TargetHost and Temporal:Namespace, defaulting to localhost:7233 and default.
• The EasyQuery middleware (MapEasyQuery) is left untouched — wrapping it in Temporal would require a larger refactor as noted in the task description.
• .NET SDK was not available on the build machine, so local compilation was not verified. CI will validate the build.
