Headless status updates from cloud sessions can now include a serving notice message

What

The internal format for status updates sent during headless, cloud-hosted sessions (the stream-json status frames) now documents a notices field, which can carry a short serving notice message. This joins existing fields covering the serving word/reason, connection status, tool calls, and directory sync.

Why

This gives cloud sessions a channel to surface a short informational notice alongside their regular status, rather than only the fixed set of fields that existed before.
