/**
 * Vitest Performance Test Setup
 *
 * Import this file in your vitest.config.ts setupFiles to enable
 * performance testing custom matchers.
 *
 * @example vitest.config.ts
 * ```typescript
 * import { defineConfig } from 'vitest/config'
 *
 * export default defineConfig({
 *   test: {
 *     setupFiles: ['@dotdo/postgres-shared/vitest-perf-setup'],
 *   },
 * })
 * ```
 *
 * @example Usage in tests
 * ```typescript
 * import { measureTiming, measureThroughput } from '@dotdo/postgres-shared/perf-test-utils'
 *
 * describe('performance tests', () => {
 *   it('completes within baseline', async () => {
 *     const stats = await measureTiming(async () => {
 *       await someOperation()
 *     })
 *     expect(stats).toBeWithinBaseline('simple-select')
 *     expect(stats).toBeFasterThan(10) // p95 < 10ms
 *     expect(stats).toHaveLowVariance(0.5) // CV < 0.5
 *   })
 *
 *   it('meets throughput requirements', async () => {
 *     const throughput = await measureThroughput(async () => {
 *       await someOperation()
 *     })
 *     expect(throughput).toMeetThroughput(1000) // >= 1000 ops/sec
 *   })
 * })
 * ```
 *
 * Issues: postgres-9zvs, postgres-2paw
