Merge origin/main into feat/graph-data-viz

Resolve App.tsx header conflict: keep main's "Privacy-limited" badge AND the
"Team memory" graph button (both in the header action group). server.ts and
backend/package.json auto-merged cleanly — main's closeMemory/shutdown and the
graph:seed script are both preserved.
