- Added `ProcessDocumentCommand`, `ProcessDocumentHandler`, and `ProcessDocumentValidator` classes in the application layer.
Added `Asp.Versioning.Http`, `Microsoft.Extensions.Caching.StackExchangeRedis`, and `Serilog.AspNetCore` to `DocumentOperator.API` for API versioning, Redis caching, and structured logging.
Added `Ardalis.Result`, `FluentValidation`, `FluentValidation.DependencyInjectionExtensions`, and `MediatR` to `DocumentOperator.Application` for result handling, validation, and mediator pattern support.
