Codebase with Design Patterns and Software Architecture

[eduabdala]

The goal of this issue is to refactor the project to improve code readability, scalability, and overall structure. The proposed changes include:

Define and apply a suitable software architecture (e.g., MVC, Clean Architecture, or another appropriate pattern)

Implement design patterns to enhance separation of concerns, such as:

Singleton for managing the serial port

Strategy or Command Pattern for handling command dispatch

Factory or Abstract Factory for building frames/protocols

Organize the codebase into modules or folders by responsibility

Add proper documentation and comments to improve maintainability and support future contributions
