feat: rewrite TUI with bubbletea

- Replace fzf dependency with native bubbletea TUI
- Add column headers (DATE, PROJECT, TOPIC, MSGS, HITS)
- Add message timestamps in preview
- Add hit count per conversation (messages containing query)
- Add mouse wheel scrolling (context-aware for list vs preview)
- Add Ctrl+J/K for preview scrolling
- Exact substring matching instead of fuzzy search
- Right-aligned help text and result counts
