libhostpolicy.dylib not found on start of standalone Blazor WASM project in VS Code on macOS

### Describe the bug

Hi.

I've encountered an issue that I can't figure out. I've got a barebones sample repo [here](https://github.com/aspeckt-112/aspire-blazor-wasm-frontend-example).

I have a requirement to serve a standalone Blazor WASM application - not an API project that also serves the WASM - just a standalone WASM application.

In the project that I'm working on, I'm using Aspire, I've got a couple of database containers, the backend (which I don't control) running in a container, and a standalone Blazor WASM app. The example is a much stripped down version of this, but it demonstrates the issue.

If you run the example project's AppHost via `dotnet run` - it launches fine. Everything works, you can navigate to the site. If you launch it via Rider - same behavior - it launches fine, you can navigate to the site. I don't have access to Visual Studio on Windows to test it with.

In VS Code, using `1.0.2` of the Aspire plugin and `1.90.2` of the C# Dev Kit, the `webfrontend` project will fail to start with the following error:

```
2026-01-18T19:33:18.6900000Z A fatal error was encountered. The library 'libhostpolicy.dylib' required to execute the application was not found in '/Users/russell/src/aspire-blazor-wasm-frontend-example/BlazorWasmStandalone/bin/Debug/net10.0/'.
2026-01-18T19:33:18.6900000Z Failed to run as a self-contained app.
2026-01-18T19:33:18.6900000Z - The application was run as a self-contained app because '/Users/russell/src/aspire-blazor-wasm-frontend-example/BlazorWasmStandalone/bin/Debug/net10.0/BlazorWasmStandalone.runtimeconfig.json' did not specify a framework.
2026-01-18T19:33:18.6900000Z - If this should be a framework-dependent app, specify the appropriate framework in '/Users/russell/src/aspire-blazor-wasm-frontend-example/BlazorWasmStandalone/bin/Debug/net10.0/BlazorWasmStandalone.runtimeconfig.json'.
```

Please let me know If you require any additional information or replication steps.

Cheers!

### Expected Behavior

The frontend project will start and run without error, as it does when using the dotnet CLI or Rider.

### Steps To Reproduce
