Code Review

This PR bumps Microsoft.NET.Test.Sdk from 18.6.0 → 18.7.0 via Renovate. The change is a single-line version update in Directory.Packages.props. The release notes show two changes: ARM64 msdia140.dll support, and a System.Memory transitive upgrade from 4.5.5 → 4.6.3 (beneficial for AOT compat).

Findings

[Altitude / Pre-existing concern — not introduced by this PR]
TUnit.SourceGenerator.IncrementalTests/TUnit.SourceGenerator.IncrementalTests.csproj:14 — This project uses Microsoft.NET.Test.Sdk + xunit rather than TUnit itself.

CLAUDE.md states: "No VSTest — Use Microsoft.Testing.Platform only. NEVER use Microsoft.VisualStudio.TestPlatform"

Microsoft.NET.Test.Sdk originates from the microsoft/vstest repository and is paired here with xunit, which runs on VSTest. This is the only project in the repo consuming this package. This PR doesn't introduce the pattern, but approving the bump implicitly continues it. If the intent is to keep this project on xunit for incremental source-generator testing (where the xunit assert model is simpler), that's a valid exception — but it's worth a deliberate acknowledgement rather than silent continuation.

Summary

The bump itself is safe and low-risk. No correctness, cross-file, or behavioral issues — the version change has no API surface impact on TUnit's runtime. The one item above is pre-existing and should be triaged separately rather than blocking this merge.
