/**
* UndoStack provides a custom implementation of an undo/redo engine. It was originally written for GitLab's Markdown editor (`gl_form.js`), whose rich text editing capabilities broke native browser undo/redo behaviour.
*
* UndoStack supports predictable undos/redos, debounced saves, maximum history length, and duplicate detection.
*
* Usage:
* - `stack = new UndoStack();`
* - Saves a state to the stack with `stack.save(state)`.
* - Get the current state with `stack.current()`.
* - Revert to the previous state with `stack.undo()`.
* - Redo a previous undo with `stack.redo()`;
* - Queue a future save with `stack.scheduleSave(state, delay)`. Useful for text editors.
* - See the full undo history in `stack.history`.
