feat(ask): strengthen Q1-D artifact validation, add rejection tests, bypass justification

- evaluate_served_ask now validates the full Q1-D DeliveredQuestion contract:
  status == 'question_only', requires_review is True, served is False,
  answer_binding is None, question.text non-empty, question.slot_name present,
  question_path != proposal_path.  Each clause is individually testable via
  _validate_artifact() which is a pure predicate with no side effects.

- Added _MISSING sentinel to distinguish absent keys from explicit None/False
  values in 'served' and 'answer_binding' checks.

- Added load-bearing comment in _stub_response explaining why served ASK
  bypasses register decoration and realizer guard: Q1-C/Q1-D is the
  authoritative grounded renderer; mutating pre-rendered intake prose would
  be semantically incorrect.

- Expanded test_ask_serving_integration.py with:
  - Rejection tests: status='proposal_only', served=True, requires_review=False,
    non-null answer_binding, missing/blank question.text, missing/blank slot_name.
  - Exact-text bypass safety test proving stub surface == artifact text exactly
    with no register/decorator mutation and realizer_guard_status='ok'.
  - Disposition telemetry tests: default main-path stability, proposal terminal
    not reclassified, ASK branch emits 'ask', refused terminal stays 'refuse',
    ChatResponse.disposition defaults '' for backward compat.

All 440 tests pass.
