Implement complete workflow engine with BPMN subset support: Backend (erp-workflow crate): - Token-driven execution engine with exclusive/parallel gateway support - BPMN parser with flow graph validation - Expression evaluator for conditional branching - Process definition CRUD with draft/publish lifecycle - Process instance management (start, suspend, terminate) - Task service (pending, complete, delegate) - PostgreSQL advisory locks for concurrent safety - 5 database tables: process_definitions, process_instances, tokens, tasks, process_variables - 13 API endpoints with RBAC protection - Timeout checker framework (placeholder) Frontend: - Workflow page with 4 tabs (definitions, pending, completed, monitor) - React Flow visual process designer (@xyflow/react) - Process viewer with active node highlighting - 3 API client modules for workflow endpoints - Sidebar menu integration
