## What changed
- Align task titles, status, and relative update times in columns, hiding metadata at narrow widths. Highlight the full selected row and show explicit empty states.
- Share grouped row layout between rendering and paging so `PageUp` and `PageDown` move by the visible viewport, account for group headings, and stop at either end. Support paging while searching.
- Show filtered group counts, shorten long project paths, and indicate additional rows above or below the viewport.
- Display system errors as `Error` and unloaded tasks as `Inactive` instead of `Finished`.
## Testing
Add a column-layout snapshot and paging regression coverage for short lists, multiple project groups, filtered tasks during reconnection, and boundary clamping. Update existing command center snapshots for the new layout and labels.
