- Only rebuild when clear button visibility changes (not every keystroke)
- Use context.select for connection status to avoid unnecessary rebuilds
- Cache available filters list to avoid recalculating per build
- Use theme-aware colors for filter chips (light/dark mode support)
- Remove dead code (_buildListItems method - 88 lines)
- Use safe .whereType<T>() instead of unsafe .cast<T>()
