Finance.NET

Prepare a new NuGet release of Finance.NET — decide the next SemVer version, bump it, write the required release notes, and open the release PR to main. Use whenever the user mentions releasing, publishing, shipping, cutting a release, bumping the version for a release, or preparing release notes, even if they don't say "release" explicitly. Every release REQUIRES a release-notes/v<version>.md file; the deploy workflow reads it and fails without it.
