🧠 AI notes on apps — open any app and see a quick AI take on what it's about.

👤 Tap any avatar — tap a chat avatar to jump to the profile, tap a profile avatar to see it full-screen.

💬 Smoother chats — topics keep their place when refreshing, chat history loads with a tidy little spinner, and translating a message no longer takes over the screen.

🐛 Small fixes — quoted text no longer clutters the topics preview, missing translations fall back to the original text, and opening a deleted app shows a friendly "not found" instead of a crash.
