Subscribe to the detail refresh state before disabling the actions.

The detail refresh keeps stale data visible with waiting: true, but detailQuery.isPending() does not subscribe to that state. The row can therefore keep the stale enable-auto-merge action enabled while the refresh runs, allowing another host mutation before autoMergeEnabled updates.

Add a subscribing pending selector and use it for both controls.

Suggested fix 
   const detailData = useEnvironmentQuerySelector(detailAtom, selectEnvironmentQueryData);
+  const detailPending = useEnvironmentQuerySelector(detailAtom, (result) => result.waiting);
   const detailQuery = useEnvironmentQueryRefresh(detailAtom);
...
-                      disabled={actionPending || handoff !== null}
+                      disabled={actionPending || detailPending || handoff !== null}
...
-                disabled={actionPending}
+                disabled={actionPending || detailPending}

Review comment at @apps/web/src/components/chat/ThreadDetailsPrRow.tsx around
lines 521 - 525:
Subscribe to the detail refresh state in the ThreadDetailsPrRow flow by
selecting detailAtom’s waiting value, then include that pending state in the
disabled conditions for both controls. Preserve the existing actionPending and
handoff checks while preventing either control from acting on stale detail data
during refresh.
