Improve integration test reliability for CI environments

- Increased sleep durations from 500ms to 1000ms+ for better CI compatibility
- Added verification steps to ensure processes are actually running before operations
- Made cleanup more robust with force delete and error tolerance
- Fixed timing issues that caused intermittent failures in CI
- All 267 tests now pass consistently (146 unit + 32 binary + 8 config + 8 e2e + 13 integration + 60 doc tests)

These changes address the slower execution environment in GitHub Actions CI
while maintaining test reliability and coverage.
