/**
 * Detects architectural layers by grouping nodes based on tags
 * and directory structure.
 *
 * Layer detection strategy (priority order):
 * 1. Check node tags for known patterns (component, api, model, util, test)
 * 2. Fall back to grouping by first directory segment
 * 3. Root files (no directory) go to "Root" layer
 *
 * @param nodes - All graph nodes to classify into layers
 * @param edges - Graph edges (unused, reserved for future dependency analysis)
 * @returns Array of detected layers with assigned node IDs
