#372 LOW: Magic numbers should be configurable

## Issue Hardcoded values throughout codebase should be in configuration: - activity_threshold_seconds = 30 (operators.py:93) - max_iterations = 10000 (operators.py:743) - ttl_seconds=300 (orchestrator.py:162) ## Impact Cannot tune behavior without code changes. ## Fix Move to configuration file (config.ini) for easier operational tuning
