fix: Add console output for startup messages

- Print startup messages to both console and log file
- Show worker count auto-detection in terminal
- Display worker startup progress in real-time
- Print shutdown messages during graceful stop
- Fix issue where service appeared to hang with no output

This ensures users can see the startup progress in terminal
instead of only writing to log files.
