feat: replace AtlasChat with assistant-ui Thread component

- Install @assistant-ui/react and @assistant-ui/react-markdown
- components/assistant-ui/thread.tsx — full Thread UI with primitives
- components/assistant-ui/markdown-text.tsx — GFM markdown renderer
- AtlasChat.tsx — useLocalRuntime adapter calling existing atlas-chat API

Gives proper markdown rendering, branch switching, copy/retry actions,
cancel button during streaming, and a polished thread experience.
