Test Platform and Framework Detection

Determine which test platform (VSTest or Microsoft.Testing.Platform) and which test framework (MSTest, xUnit, NUnit, TUnit) a project uses.

Response contract

Honor the user's requested labels and order exactly, substituting the actual classification for every placeholder. Start with the verdict: never put a heading, scratch analysis, tool syntax, or an echoed template before it. Follow with one concise evidence sentence naming the repository facts needed to justify every requested classification. When Framework is requested, name the package or project SDK that identifies it. Use a second sentence only for a conflict, an incomplete configuration, or target-framework-specific differences.

Platform means the platform that actually executes tests: VSTest or MTP. If conflicting or incomplete configuration prevents execution, report it as unavailable rather than inventing a successful platform.
