Tasks

• Run tests locally with maxConcurrency: 2 and verify zero "unexpected mock call" failures
• Profile memory usage during local runs
• Update vitest.config.ts: maxConcurrency: isCI ? 2 : 4
• Run 20 consecutive CI builds and verify 100% pass rate
• Monitor memory usage (must stay <5GB) and measure speedup
