OS Update Role

This role manages system updates on Debian-based systems using the apt package manager. It provides controlled system maintenance operations including package updates, upgrades, and cleanup.

What it does

The role performs the following operations based on configuration:

Autoremove: Removes unused packages and dependencies
Update: Updates the package list and upgrades all packages to their latest versions
Upgrade: Performs a distribution upgrade (equivalent to apt upgrade)

Each operation is controlled by boolean variables, allowing you to selectively enable or disable specific maintenance tasks.
