fix: progress ticker on tool-activity, last-line └, summary+description both shown

- Ensure progressTicker runs during tool-activity updates for time refresh
- Last activity line uses └ instead of ├
- Summary (📋) and description shown together when both present
- Description indented as sub-item under summary
