chore: replace print() with proper logging; add jitter to automation

- CLI commands: replace print with click.echo (ensures proper stdout handling)
- Coordinator API services: add logging import and logger; replace print with logger.info
- Automation scripts: claim-task.py, monitor-prs.py, qa-cycle.py now use logging and have random jitter at startup
- Also includes fix for name shadowing in regulatory.py (aliased service imports) which was pending

This addresses issue #23 (print statements) and improves error handling.

Note: Many bare except clauses (issue #20) remain; will be addressed separately.
