feat(cli): add ProgressBar to queue command for batch job processing

Integrate ProgressBar into queue.zig for multi-job queuing:
- Show progress bar when queuing 2+ jobs (not in JSON mode)
- Update progress after each successful job queue
- Maintain simple output for single job queuing
- Clean up output for batch operations

Benefits:
- Better UX for batch job queuing
- Visual progress indication for long operations
- Consistent with sync command ProgressBar pattern

All tests pass.
