test(dlx): fix flaky test and update coverage badge

- Fix listDlxPackagesAsync test to handle extra files/directories
  - Changed from exact count (2) to >= 2 to be more resilient
  - Test was failing due to .dlx-manifest.json.lock or similar files

- Update README coverage badge: 83.02% → 83.06%
  - Reflects new test coverage from recent additions
  - 40 new tests added across 4 files (prompts, lifecycle, types, defaults)
