- Add explicit test timeout (15s), hook timeout (10s), and teardown timeout (10s) to vitest config
- Configure retry logic for CI environments to handle occasional flaky tests
- Add asyncUtilTimeout configuration to testing library to fail faster
- Resolves issue where tests would hang indefinitely in CI showing dots continuously
