Proactivity level is threaded through session state, permission modes and the init message, but always empty.
Proactivity plumbing reaches the init message, but the function producing the emitted field returns undefined.
What's wrong with this entry?
Session state gained a proactivity-level change notification, permission-mode resolution now also returns a proactivity value and whether the mode was supplied on invocation, relaunch passes that value along, and the system init message accepts a proactivity state. The function that turns that state into the emitted field is empty and returns undefined, so nothing is reported.
- No flag gates the plumbing; only the serializer is a no-op.
