/**
 * Auto-Layout for Agent Spec Flows
 *
 * Agent Spec has no visual position information. This module assigns
 * positions to imported nodes using a layered layout algorithm:
 *
 * 1. Topological sort from StartNode using control-flow edges
 * 2. Assign layers based on longest path from StartNode
 * 3. Position nodes with configurable spacing
 * 4. Fan out branches vertically from BranchingNode
