jens 788ddcd0b5 feat: Implement comprehensive architectural guidelines and clean code standards
- Establish feature-based architecture with clear separation between Logic, Data, and Shared layers
- Define directory structure conventions for controllers, entities, DTOs, managers, mappers, models, processors, providers, repositories, and services
- Implement Symfony 7.4+ compliance with proper Request handling (UI layer only)
- Enforce PHP 8+ attributes usage instead of annotations
- Set up proper DTO usage in UseCases with immutable properties
- Configure repository pattern with interfaces in Logic layer and implementations in Data layer
- Implement strict separation of concerns with UI layer handling Request objects exclusively
- Define clear naming conventions (PascalCase for feature names)
- Add shared components directory for reusable elements across features
- Establish HTTP status code constants usage instead of magic numbers
- Configure proper file placement for controllers in UI/Frontend, UI/Api, and UI/CLI subdirectories
- Enforce modern PHP practices with explicit return types and strict typing

This commit lays the foundation for a maintainable, scalable Symfony 7.4+ application following clean architecture principles and modern coding standards.

description: Defines best practices for handling HTTP requests in Symfony 7.
Ensures strict separation of concerns by transforming raw request data into
immutable DTOs at the boundary of the UI layer, preventing leakage of
infrastructure details into business logic.

The Request object must only be used in the UI layer (Controllers). Immediately convert request data into DTOs located in /src/Logic/[FeatureName]/DTO before passing them to UseCases. Use $request->getPayload() for JSON APIs, $request->query/request for forms, and $request->attributes for route parameters. Never pass the Request object to Logic or Data layers.
