Refactored FriendsController to provide more precise error responses and input validation. Enhanced FriendsService to handle new exception types and improved user search logic. Added tests for user search, updated repository to throw on empty search results, and implemented User equality override. Cleaned up Program.cs controller JSON options.
Introduced a UsernameValidator with Cyrillic and length checks, integrated into AuthService and registration flow. Added InvalidUsernameException and related interface. Updated User model to support friend requests, added FriendsController (stub), and configured Friendship entity in EF Core. Adjusted UserValidator max name length and removed navigation properties from PrivateChat.
Introduces Friendship and PrivateChat models, repository interfaces, and implementations for managing friendships. Adds validators and comprehensive unit and integration tests for friendship logic. Updates InviteUserController with new endpoints and restricts access to admin role. Removes unnecessary project references from Govor.API.csproj and registers new DbSets in GovorDbContext.
Moved service implementations and interfaces from Govor.API and Govor.Core to new Govor.Application and Govor.Contracts projects. Updated namespaces and references throughout the solution. Added custom exception classes for authentication and invite services. Adjusted dependency injection and project references to use the new structure. This refactor improves separation of concerns and prepares the codebase for better maintainability and scalability.
