V0.12.0/dotnet new major bump

[gimlichael]

This pull request introduces the native Microsoft Testing Platform test stack alongside vendor-neutral agent guidance for both .NET scaffolds. Generated solutions resolve compatible Codebelt 12.x and xUnit 4.x lines with Codebelt Coverlet coverage, while root AGENTS.md becomes the single instruction contract. Validators and documentation record both contracts for reviewers.

Native test stack:

• Generated solutions use compatible major test lines with central versioning and coverage diagnostics
• New projects select the native runner and verify discovery plus test and coverage output for each executable target
• Host behavior is exercised through managed fixtures without legacy blocking types or extra report packages

Vendor-neutral agent guidance:

• Generated repositories carry a single vendor-neutral instruction contract with complete governance examples preserved
• Vendor-specific instruction files are removed from manifests, inventories, and bot-workspace pointers
• Coding, testing, coverage, benchmarking, documentation, and workspace rules stay intact without summarization

Scaffold guidance:

• Scaffold instructions define compatible version lines, runner selection, and required shared inventory for both solution types
• Reference guides describe the required output tree and testing approach without optional omissions
• Evaluation expectations require the single instruction source and the coupled test contract

Validation and regression coverage:

• Validators enforce runner selection, package references, instruction inventory, and complete governance examples
• Regression coverage builds representative scaffolds and checks inventory, guidance, discovery, and coverage output

Documentation:

• Root documentation surfaces both the native test stack and the single instruction contract for consumers

### Issue 1
skills/dotnet-new-app-slnx/assets/app/console/Program.minimal.cs:6
The changed public `Program` class has no XML documentation comment. Repository instructions require XML comments on all public classes, so this requirement must be satisfied before merging.

Summary

The PR moves both .NET scaffolds to xUnit 4, Codebelt 12, native MTP testing and a single generated AGENTS.md instruction contract.

• Adds scaffold build, discovery and coverage regression checks, including framework-selection and incompatibility cases.
• Updates package-resolution guidance, validators and consumer documentation.
