Garry Tan 7757233d53 test: expose high-water-mark flags through PlanSkillObservation
The 2KB obs.evidence window often misses the prose-AUQ moment because
ExitPlanMode UI ("Ready to execute" + numbered approve/reject prompt)
pushes the model's earlier option list out of the tail by the time
outcome=plan_ready fires. Tests checking "did the user see a question"
need to consult historical state, not just the truncated final tail.

Adds two optional fields to PlanSkillObservation:
  - proseAUQEverObserved: true if isProseAUQVisible was true at any tick
  - waitingEverObserved: true if the LLM judge ever returned 'waiting'

The 4 plan-mode --disallowedTools tests now check these flags as part
of the surfaceVisible computation:
    isProseAUQVisible(obs.evidence) || obs.proseAUQEverObserved === true
    blockedVisible || proseAUQVisible || obs.waitingEverObserved === true

This catches the autoplan / plan-ceo / plan-eng case where the model
surfaces options briefly, fails to get a response, then keeps thinking
— eventually emitting ExitPlanMode and pushing options out of evidence.
