Refactor console client to new Govor.ConsoleClient project

Removed Govor.Console implementation and introduced a new Govor.ConsoleClient project with a modular command-based architecture. Added dependency injection, command dispatcher, middleware pipeline, logging, and interactive command support. Updated solution and project files to reflect the new structure.
