Merge origin/main into main

Resolved 2 messenger conflicts:
- FriendsMessengerView.tsx: union — kept local typingUserIds/sendTypingStatus
  from useMessenger() plus upstream's useFriends().getFriend.
- FriendsView.css: kept local group-chips + typing-indicator styles (upstream
  empty there).
Vitest 545/545 green. (typecheck TS2307 is the un-linked renderer, env-only.)
