/**
 * MCP Hub REST API tests (UX-Refactor Phase 4, S08/S17).
 *
 * Harness mirrors the Phase-3 automations/agents style: bare Fastify + real
 * stores (MindDB ':memory:' InstallAuditStore, real McpRuntime with the same
 * DI'd PassThrough mock-spawn the agent runtime tests use, real tmp-dir
 * .mcp.json store) + the REAL route plugins, exercised via server.inject.
 *
 * The install path registers the REAL marketplaceRoutes over a minimal real
 * better-sqlite3 packages table so delegation runs the production SecurityGate
 * + installer code — including the M2 regression (a CRITICAL block must now
 * PERSIST its audit row instead of silently failing the risk_level CHECK).
