Zarhus OS: Base OS – Buttons interface support (keyboard standard input)

This product aims to implement support for the buttons interface in the Zarhus OS. The primary goal is to configure buttons to function as arrow keys, ensuring that button presses are recognized and processed like standard keyboard inputs. This approach allows web browsers and applications to interpret button presses without requiring any customization.

Features:
• Zarhus OS meta-layer with device tree configuration to integrate buttons as standard keyboard input.
• Documentation that describes the setup of the development hardware.
