Master archived three Agent Notes this branch had fact-updated (archived
copies restored to their frozen master content; the pills note now links
the archived path), extended the steer-all placeholder to continuable
children (spec and subagent e2e take master's behavior with this branch's
reworded copy), and dropped the session-sharing sentence from feedback
acks (goldens re-refreshed with the new placeholder).
