Workflow Builder: Simulator

Built a new simulation engine with time acceleration, persistent state across page refreshes, and a console panel for debugging and database management. This prepares the way to test more realistic flows.

• Time acceleration — 1x/60x/3600x speed options for testing long-running workflows
• Configurable batches — Adjustable batch sizes with automatic event processing
• Simulator config — Customizable contact attributes and event payloads
• Console drawer — Simulator/Database tabs with table counts, individual clear buttons, and “Clear All Data”
• Inline controls — Batch | Speed | Start/Stop with play/stop icons
• Persistent state — Simulator state survives page refreshes and navigation; workflows continue from where you left off
• Wait step improvements — Uses accelerated simulator time with accurate completion counts
