feat(ui): add trigger word highlighting for selected LoRAs

- Import applySelectionHighlight in lora_loader and lora_stacker
- Pass onSelectionChange callback to loras_widget to handle selection changes
- Implement selection tracking and payload building in loras_widget
- Emit selection changes when LoRA selection is modified
- Update tags_widget to support highlighted tag styling

This provides visual feedback when LoRAs are selected by highlighting associated trigger words in the interface.
