Idle Service: Use the Idle Notify Wayland API natively #64
Description
This task serves to replace the usage of SwayIdle.
Way-Shell can start listening to [https://wayland.app/protocols/ext-idle-notify-v1](Idle Notify) protocol to understand when the current seat has become idle.
From there we can map into useful functions like dimming the screen and running external scripts/applications.
This is a depedency on implementing our own screen lock service, as it provides the events to trigger our lock.
