fix: TUI spacebar + improved design

Switch to bubbles textinput for proper keyboard handling (space,
cursor, backspace, clipboard all work correctly).

Improved design:
- ❯ user prompt, ◆ assistant prefix, ✗ error prefix
- Word wrapping for long responses
- Separator line between chat and input
- Streaming indicator (● streaming) in status bar
- Better color scheme (lighter purples/blues)
- Welcome message with usage hints
