- Added a helper that renders hub output and extracts ordered agent IDs.
- Replaced positional string assertions with explicit row-order expectations.
- Awaited asynchronous theme initialization in test setup.
- Captured each row's initial position in AgentHubOverlayComponent on first refresh and reused it on later refreshes.
- Changed subsequent sorting to prioritize status then prior row position, so activity updates no longer reordered visible rows.
- Added a regression test that verifies row ordering stays stable when activity changes and new agents append at the end.
