/**
 * test_performance_latency.ts — Story 12.4
 *
 * Lightweight latency benchmark for OpenLife hot paths. Measures P50/P95/P99
 * for a handful of deterministic operations and persists a baseline at
 * `.artifacts/perf-baseline.json`. Fails if any P95 regresses more than
 * the configured threshold (default 30%) vs the saved baseline.
 *
 * Design constraints:
 *   • runs inside `test:all` → must complete in <5s end-to-end
 *   • no CLI spawn — measures library code directly to keep variance low
 *   • baseline auto-seeds on first run; later runs compare
 *   • configurable threshold via PERF_REGRESSION_THRESHOLD_PCT (default 30)
