fix(ci): seal 10th fix-forward — migrate 5 fragile-path test offenders to repo_root helper

W588 drift-guard caught 5 tests added this session using `Path(__file__).parents`
walk instead of the canonical `tests._helpers.repo_root.repo_root()` (W572).
Migrate all 5 mechanically — same `Path(__file__).resolve().parent.parent` →
`repo_root()` shape established by W587/W594:

  - test_sarif_tag_coverage.py:60
  - test_w675_example_smells_suppress.py:24
  - test_w676_followup_example_files.py:40
  - test_compound_recipe_registry.py:85
  - test_w1083_followup_adopters.py:156

cli.py count refresh (208→241) is the session baseline, folded in.
