Dependency Update Review: Microsoft.NET.Test.Sdk 18.3.0 → 18.4.0

This is a routine Renovate Bot dependency bump — a single-line change in Directory.Packages.props.

What's in v18.4.0

Highlights from the release notes:

• Fix .NET 10 regression for traits — directly relevant since TUnit multi-targets net10.0; this fix is worth having.
• LoongArch64 support — no impact on TUnit.
• Target framework updates to net10.0/net11.0 — aligns with TUnit's direction.
• Condition evaluation refactor — internal change, no API impact expected.

Scope

The package is only referenced in one project:

TUnit.SourceGenerator.IncrementalTests/TUnit.SourceGenerator.IncrementalTests.csproj

This is the Roslyn source generator incremental test project. The Roslyn testing infrastructure requires Microsoft.NET.Test.Sdk as a host, so its presence here is expected and appropriate — it doesn't conflict with the project's "no VSTest in engine" rule.

Verdict

The change is minimal and safe. The .NET 10 traits regression fix is a concrete improvement. No concerns — good to merge once CI passes.
