Log exception when app fails to start in CLI

[ODukhno]

There is a misleading logging that happens under the following conditions:

1. We use .NET app with minimal hosting model
2. We use dotnet tool in our csproj file like this:

3. We introduce an issue in our Program.cs, so the application just cannot start up.

We receive an error like the following:

AI.Crawl.Client -> C:\Users\oldukhno\work\Invictus\artifacts\bin\AI.Crawl.Client\debug_net10.0\AI.Crawl.Client.dll
AI.Search.Services.Internal -> C:\Users\oldukhno\work\Invictus\artifacts\bin\AI.Search.Services.Internal\debug_net10.0\AI.Search.Services.Internal.dll

This is misleading and hiding the actual issue. We had better output the error message to stderr instead just swallowing it.
