fix(security): resolve CodeQL alerts for logging, URL sanitization, and workflow permissions

- Remove api_key debug print blocks from relation_extractor.py and triplet_extractor.py (CWE-532 clear-text logging)
- Replace URL substring check with exact equality in test_web_ingestor.py (CWE-20 incomplete sanitization)
- Add `permissions: contents: read` to benchmark.yml and security.yml workflows (least-privilege)
