Pipeline

[JosLopes]

An implementation of a pipeline so tasks with multiple programs can be executed!

[voidbert]

There is a module called task_runner with a TODO comment telling to add pipelines there. Please move your code there and delete this module. Pipelines and single comments run in the same way

[voidbert]

Please remove the first and last process separate conditions and integrate them all into the same for loop with the if statement inside. This way, you avoid a lot of bloat in the exec phase. See https://github.com/ruilopesm/System-Monitor-SO/blob/main/src/tracer.c#L244 as inspiration, if it helps you.

Don't mind with the changes. I found a very elegant solution online and fixed a file descriptor leak in it.
