fix(plan-lifecycle): fix integration test regressions from DoD gating

Update integration test helpers to use definition_of_done values that
satisfy the new TextMatchEvaluator gate (criterion text must appear as
a substring of a plan argument key or value).  Also fix _evaluate_dod
to merge DoD metadata into plan.validation_summary without overwriting
Execute-phase validation counts, preserving the coverage/tool-validation
gate used by apply_with_validation_gate.  Update CONTRIBUTORS.md.

Fixes: wf02, wf04, wf06, wf07 integration test suites.
