/**
* Interface for full-featured desktop automation controllers.
*
* Automaton combines capabilities from other interfaces to create a controller that can:
*
* - Get desktop and mouse state information like pointer location via [DesktopController]
*
* - Perform mouse and keyboard input like clicks, key presses, and scrolling via [InputController]
*
* - Handle timing and delays between actions using [TemporalController]
*
* By composing multiple capabilities, Automaton aims to provide a simple yet powerful interface for implementing
* desktop automation routines.
*
* Typical usage involves:
*
* 1. Obtaining an Automaton instance bound to the current OS/desktop
* 2. Calling methods like [moveMouse] and [mouseClick] to perform actions
* 3. Using [sleep] and [sleepWithVariance] to add delays
*
* This interface allows the underlying OS/desktop implementation details to be abstracted and swapped as needed.

* For example, if a target destination point is (100, 200), the wiggle params
* might generate an actual movement point like (102, 198) to add some randomness.
