fix: suggestions below chat + hide raw JSON during streaming

- Suggestions moved from above chat to below (before input) — agent
  reads summary first, sees suggestions after AI responds
- During streaming, the last assistant message (raw JSON) is hidden —
  only the typing indicator shows. Once complete, parsed message renders.
