lint: address Copilot review on #460 (encoding, docstring, CURIE-parent DEF-FORM)

- check_definition_form now compares the genus only against LABEL-form parents;
  CURIE-form parents (governed by PARENT/HOUSE-STYLE) no longer trigger a spurious
  DEF-FORM mismatch.
- baseline write_text/read_text use encoding='utf-8' for deterministic CI.
- docstring corrected: the ratchet is '--baseline PATH --write-baseline'.

+Baseline ratchet: ``--baseline PATH --write-baseline`` records the currently-accepted findings;
 a later run with ``--baseline PATH`` fails only on findings BEYOND that floor, so a
 large existing-debt audit can gate new additions without first paying down the debt.
 Regenerate the baseline as debt is fixed -- the count can only go down.
