feat: show one row per conversation with improved search

- Display one row per conversation instead of per message
- Sort by most recent activity (LastTimestamp)
- Search across all user messages in conversation
- Preview shows all matches with context, truncating gaps
- Add CI test workflow (reused by release workflow)
- Improve test coverage to 39%
