Undo/Redo History Overview

What Is Tracked

How It Works

// The history middleware intercepts tracked mutations:
// 1. Before the mutation: take a snapshot of { nodes, edges }
// 2. Push snapshot onto the undo stack
// 3. Apply the mutation (workflowStore state changes)
// 4. Clear the redo stack (new action invalidates redos)

// Undo (Ctrl+Z):
// 1. Pop the undo stack → get previous snapshot
// 2. Push current state to redo stack
// 3. Restore workflowStore.nodes and .edges from snapshot

// Redo (Ctrl+Y):
// 1. Pop the redo stack → get next snapshot
// 2. Push current state to undo stack
// 3. Restore workflowStore.nodes and .edges from snapshot
