/**
 * Link Step — ported from KB sleep/steps/link.ts.
 *
 * Builds Memory→Memory edges based on Jaccard tag similarity:
 * - Computes Jaccard similarity between tag sets for all memory pairs
 * - Creates an Edge when similarity >= minConfidenceForLink
 * - Respects maxEdgesPerMemory cap via neighbor count tracking
 * - Same-source-directory and shared-tag-count boosts mirror KB
 *
 * Adapter note: KB stores edges in sleep.db memory_edges. Arcana uses
 * deps.structured.storeEdge (StructuredStore). getNeighbors is used to
 * check the current edge count for a memory.
