Migrate codebase to use SmartRes Result<T, Error> (and Unit) across services and interfaces, replacing previous Result usage and updating many method signatures and implementations. Add ResultExtensions to convert SmartRes results to ASP.NET ActionResult and refactor AuthController to use functional Bind/Tap chains for registration/login flows. Upgrade projects to .NET 10 and bump related NuGet packages; add libs/SmartRes.dll and project references. Simplify DbContext registration to use Npgsql only with retry policies and enable detailed logging. Update Swagger/launch settings and other minor fixes (AutoMapper registration change, whitespace/exception handling, and removal of the Govor.ConsoleClient files).
Large refactor that renames/moves core types into a new Govor.Domain surface and reorganizes the Application layer. Models, configurations, migrations and many files moved from Govor.Core/Govor.Data to Govor.Domain; numerous Application services, interfaces and implementations were relocated or added (authentication, friends, messages, medias, push notifications, user sessions, storage, synching, private chats, etc.). Tests updated to use Govor.Domain namespaces and adjusted project references (removed Govor.Data reference from API tests). Also updated API, Hub and mapping code and project files to reflect the new structure and naming. This is primarily a codebase-wide namespace and module reorganization to establish a Domain project and restructure application services.
