Subject: [PATCH] fix(ai): notify all tabs when a pending question is answered
 (#22491)
MIME-Version: 1.0
Content-Type: text/plain; charset=UTF-8
Content-Transfer-Encoding: 8bit

## Rationale

`resolvePendingQuestion` updates the question tool-part to `answered`
and re-claims the thread — but publishes **nothing**. The answering tab
converges via a local browser event; every other tab keeps rendering the
question card as interactive until the resumed stream's first chunk
happens to arrive. A second tab (or teammate view on shared context) can
attempt to answer an already-answered question and hit a confusing
`QUESTION_NOT_PENDING` error.

## Why this is the root cause, not a symptom patch

Answering a question is a state transition every subscriber cares about
— exactly like queue promotion, message persistence, and stream errors,
all of which publish. This transition just never did. The fix publishes
the existing refetch-trigger event (`queue-updated`, which every tab
already handles by refetching messages + thread state) right after
resolution — no new event type, no new client code path, consistent by
construction with how every other transition converges tabs. A dedicated
`question-answered` event carrying the answers would save one refetch
round-trip; the audit's verdict was that's over-engineering for a rare
interaction.

Publishing *before* the resume-enqueue is deliberate: even if the
enqueue fails, the question **is** answered server-side, and tabs should
reflect server truth.

## User impact

Second tabs stop offering an interactive question that will error when
submitted; everyone sees the answered state within a refetch instead of
whenever the stream resumes.

## Test plan

- [ ] CI green
- [ ] Manual: two tabs on one thread, answer the question in tab A → tab
B's card flips to answered without interaction
