Added tap-to-follow-up to my AI chat app — ask follow-ups in their own branches

Hey fellow indie makers 👋

Been building YeeroAI (an AI chat app with 300+ models side-by-side) as a solo project. Ran into a problem I see in every AI chat product: you're chatting and something in the reply doesn't quite make sense, so you want to ask a follow-up. But then you either copy-paste into a new chat and lose context, or keep asking in the same thread and it gets messy.

So I added tap-to-follow-up. Select any text in an AI reply, fire off a follow-up right there. Each follow-up runs in its own branch — separate context, no pollution to the original conversation. You can always trace back to see the full chain of reasoning.

Also snuck in a small QoL fix: knowledge base, memory, and prompt cards now collapse from the title bar. No more scrolling to the bottom. Tiny change, big difference in daily use.

Past highlights for context:

- 300+ models, side-by-side
- Git-style conversation branching & tree view
- Knowledge base + memory injection
- Background streaming
- ⌘K search & quick actions
- AI-generated web apps
- Drag-select batch ops
- Pinned tabs
- Patch-style incremental updates
