feat(lora-cycler): implement batch queue synchronization with dual-index mechanism

- Add execution_index and next_index fields to CyclerConfig interface
- Introduce beforeQueued hook in widget to handle index shifting for batch executions
- Use execution_index when provided, fall back to current_index for single executions
- Track execution state with Symbol to differentiate first vs subsequent executions
- Update state management to handle dual-index logic for proper LoRA cycling in batch queues
