Add support for workflow triggers to determine start node: - Modified execution_order.py to accept optional start_node_id from triggers - Updated N8NExecutor to use triggers for determining workflow entry point - Added helper function to find start node from enabled manual triggers - Created comprehensive tests for trigger-based execution - Maintains backward compatibility when no triggers are specified Co-authored-by: johndoe6345789 <224850594+johndoe6345789@users.noreply.github.com>
