This updates the Aspire AppHost to use Aspire 13 publish-time container file injection for frontend assets, replacing the previous esproj-based coupling. The frontend build output is now modeled as an AppHost resource relationship instead of an MSBuild project reference.

• AppHost publish wiring

  • Define the frontend once as a Vite resource and wire it into the StaticHost publish artifact:

  var frontend = builder.AddViteApp("frontend", "../../frontend")
      .WithPnpm();
  
  var staticHostWebsite = builder.AddProject<Projects.StaticHost>("aspiredev")
      .WithExternalHttpEndpoints();
  
  staticHostWebsite.PublishWithContainerFiles(frontend, "./wwwroot");

  • Keep local run-mode frontend endpoint behavior under IsRunMode using the same frontend resource.

• Remove esproj dependencies

  • Removed ../../frontend/frontend.esproj ProjectReference from src/statichost/StaticHost/StaticHost.csproj.
  • Removed src/frontend/frontend.esproj from Aspire.Dev.slnx.

• Resulting resource model

  • Publish-time frontend artifact flow is now explicit in AppHost (frontend ➜ aspiredev ./wwwroot) via PublishWithContainerFiles, aligning the solution with Aspire 13 container-files publishing.
