Git NuGet README

This skill creates or updates a package-facing README.md for a .NET repository by combining git history, actual project/package metadata, and concrete source-level capabilities. It improves the developer experience by pulling install guidance, package value, and a quick start closer to the top while keeping branding and tone derived from the current repository rather than from any hardcoded ecosystem template.

Read references/nuget-readme-blueprint.md before writing or rewriting the README.
