[Luis Quintanilla (luisquintanilla)]

Summary

• add the first .NET 10/componentize-dotnet Wassette example
• add shared build, WIT documentation, validation, and registry wiring
• keep registry pull requests structural-only until a successful publication makes OCI artifacts available

This is the first focused contribution for #871. It intentionally contains only the deterministic, credential-free time-server-dotnet component; later capability-focused examples will be proposed as separate PRs after this foundation is reviewed and merged.

Scope

• time-server-dotnet exports the time-server WIT world and imports the WASI wall clock.
• Shared MSBuild properties pin .NET 10, componentize-dotnet, NativeAOT/LLVM, and the required NuGet feeds.
• The root build and example workflow restore/build, inject WIT documentation, validate components, and publish the first .NET registry artifact.
• The cookbook documents WIT selection, generated bindings, NativeAOT/WASI constraints, policies, validation, and why file-based apps are not used for exported components.
• Registry validation checks JSON structure on pull requests and dereferences OCI components after successful publication on main, avoiding false failures for unpublished draft artifacts.

Validation

• dotnet restore and Release build succeeded.
• wasm-tools validate and component WIT inspection succeed before documentation injection; final artifact validation succeeds after injection.
• GitHub Actions Publish Examples build passed for this branch.
• GitHub Actions registry validation passed for the structural pull-request path.
• JSON/XML checks, documentation-link checks, and git diff --check passed.
• Local just, wasm-tools, and wit-docs-inject were unavailable; CI supplied those checks.
• The NuGet vulnerability endpoint was unavailable locally, producing only NU1900 warnings.

Notes

The .NET toolchain is preview-oriented. This PR does not add credentials, live API dependencies, generated bin/obj outputs, or the MCP client from the standalone wassette-dotnet repository.
