/**
 * Marketplace Dev Integration Seam Tests
 *
 * Proves 4 integration seams without changing any user-facing surface:
 * 1. Catalog backend seam — MarketplaceDB.search() returns packages
 * 2. Security/trust seam — SecurityGate runs heuristic scan
 * 3. Pack reconciliation seam — packs are queryable
 * 4. DB seed seam — marketplace.db exists and is queryable
