Optimize CI: add NuGet caching and build artifact sharing

Refactored ci.yml to cache NuGet packages and upload build artifacts in the build job. Test and coverage jobs now download and use these artifacts, eliminating redundant restore/build steps. Updated job dependencies and streamlined the publish job for improved efficiency and faster CI runs.
