Goal

Publish HttpClient.Resilience.Analyzers version 0.1.0-preview.1 to NuGet.org.

Current evidence

• Local package validation passes for artifacts/packages/HttpClient.Resilience.Analyzers.0.1.0-preview.1.nupkg.
• Hosted CI passes on main.
• Release workflow dry-run passes with publish=false.
• NUGET_API_KEY is not currently configured as a repository secret.

Required steps

1. Create a NuGet.org API key with permission to push HttpClient.Resilience.Analyzers.
2. Add it as the repository secret NUGET_API_KEY.
3. Trigger the Release workflow with publish=true, or create and push tag v0.1.0-preview.1.
4. Verify the package appears at https://www.nuget.org/packages/HttpClient.Resilience.Analyzers/0.1.0-preview.1.

Acceptance criteria

• NuGet.org shows version 0.1.0-preview.1.
• The release workflow completes successfully on the publishing run.
• The README NuGet badge resolves to the published package.
