The desktop CI workflow previously kept its build/test commands in YAML separately from the local build. Route the existing six offline test runs through a compiled Cake Frosting entry point while retaining their parallel jobs, matrix labels and credential/setup coverage. The package job now also prepares and verifies the five application bundles.

The public publishing workflow, shared desktop/processor validation gate, publication lock, runtime dependencies and library version remain unchanged. The artifact-only target runs no tests and publishes nothing; regression coverage checks its dependency graph so validation reuse can be retained when release preparation is integrated later.

Validation:

• Hosted CI run 41244078546 passed all eight jobs for head 71a0648. Independent download/readback of all seven TRX reports confirmed 1,309 product cases and 19 build-tool cases passed, with no failed or skipped cases. The workflow completed in approximately 2 minutes 25 seconds; this single run is not a controlled speed benchmark.
• The retained package artifact contains one API-validated NuGet package and five application bundles. Package DLLs match the standalone release DLLs; no Cake runtime dependency was introduced. The artifact-only receipt correctly records that it ran no desktop tests and performed no publication.
• The original full local pilot passed all 1,309 desktop cases, package/API validation and comparison of all 228 artifact payload entries against a clean reference built by the existing release commands. The CI suite selector and artifact-only entry point also passed locally.

The NUnit configuration policy passed. No processor test, public package release or default-branch merge was performed. This draft is ready for review.
