make run
All control characters are implemented, you can change the font color and the background color, and scrolling also works.
A timer is displayed at the top right of the console.
I have implemented the shutdown and write system calls.
For the processes, I have implemented a collaborative system, the processes themselves must call schedule(). To test the processes, I added 5 simple processes (they increment a counter and display it), the first one is started on launch.
