Update CI for .NET 10, add tests and project reference

- Update build-and-release.yml: use actions/checkout@v4, switch to .NET 10, fix asset paths, and replace deprecated set-output usage
- Add ProjectReference to Reina.Cryptography in test project
- Add LibraryTests.cs with xUnit tests for input validation and placeholders for future tests requiring mocks
