SelectArray and SelectArrayOrThrow utility methods

[viklover]

I would like to add methods SelectArray<T> and SelectArrayOrThrow<T> to JsonHelper (also don't forget about extension methods and test)

Task List

• Analyze requirements and codebase patterns
• Add SelectArray<T> and SelectArrayOrThrow<T> to JsonHelper.cs
• Add extension methods to JTokenExtensions.cs
• Add tests to JsonHelperTests.cs
• Add tests to JTokenExtensionsTests.cs
• Build and run tests to verify

Progress

I've analyzed the codebase and understand the patterns. Starting implementation now.

SelectArray<T> will follow the same pattern as SelectList<T> but return T[] instead of List<T>.

Task List

• Gather context from codebase and understand existing patterns
• Add SelectArray<T> and SelectArrayOrThrow<T> to JsonHelper.cs
• Add extension methods to JTokenExtensions.cs
• Add tests to JsonHelperTests.cs
• Add tests to JTokenExtensionsTests.cs
• Build and run tests to verify

Summary

Implemented SelectArray<T> and SelectArrayOrThrow<T> methods following the exact same pattern as SelectList<T> / SelectListOrThrow<T>:

• JsonHelper.cs — Added SelectArray<T>(JToken, string) returning T[]? and SelectArrayOrThrow<T>(JToken, string) returning T[]
• JTokenExtensions.cs — Added corresponding extension methods SelectArray<T>(this JToken, string) and SelectArrayOrThrow<T>(this JToken, string)
• JsonHelperTests.cs — Added SelectArrayWithStringsTest with a test case for a string array
• JTokenExtensionsTests.cs — Added SelectArrayWithStringsTest with a test case for a string array

The implementation uses token.ToObject<T[]>() for deserialization, which is naturally supported by Newtonsoft.Json.

Note: Could not run dotnet test due to shell execution permission restrictions. The changes strictly follow the existing codebase patterns and should build cleanly.
