/**
 * Smart api test runner.
 *
 * Optimizations (CI / QUINN_REQUIRE_DB_TESTS):
 *   - One TEMPLATE database with all test migrations applied once per run
 *   - Per-file DBs cloned via CREATE DATABASE … TEMPLATE (~seconds, not ~20s migrate)
 *   - Parallel workers (QUINN_TEST_WORKERS, default 4 on CI)
 *   - QUINN_CI_FAST=1 runs a smoke subset on push/PR; workflow_dispatch runs full
 *
 * Off-LAN: probes DB latency and skips DB-dependent files when slow/unreachable.
