feat(tui): show tool output in terminal and python renderers

- Terminal renderer now displays command output with smart filtering
- Strips PS1 prompts, command echoes, and hardcoded status messages
- Python renderer now shows stdout/stderr from execution results
- Both renderers support line truncation (50 lines max, 200 chars/line)
- Removed smart coloring in favor of consistent dim styling
- Added proper error and exit code display
