feat(chat): add interactive TUI with Bubble Tea and streaming

- Replace basic CLI chat with Bubble Tea-based TUI featuring viewport, textarea, colored history, and streaming replies.
- Add StreamSilent method to client for TUI integration without live printing.
- Introduce model flag for chat command.
- Update dependencies to include charmbracelet libraries.
