Jevotron: Multiple Jev integrations from the command line

Jevotron scans CSV, YAML, JSON, TOML, text, OBO, and gzip files from the command line, producing field-level anomaly scores and a review queue. It caches results in SQLite, allowing unchanged entries to be reused and thresholds to be adjusted without re-scanning. In a sample of 24 public traces, Jevotron matched 79.8% of step-quality labels, achieving 89.7% precision and 70.3% recall on harmful steps.
