Add protocol deviation graph guard

[Jorel97]

/claim #17

Summary

• Adds a distinct protocol-deviation-graph-guard/ slice for Scientific Knowledge Graph Integration.
• Audits synthetic experiment/protocol/dataset graph packets before graph edges and recommendations publish.
• Flags missing required protocol steps, protocol-version mismatch, expired calibration, unauthorized reagent lots, and parameter deviations outside tolerances.
• Emits deterministic JSON, Markdown, SVG, GIF, and MP4 reviewer/demo artifacts from synthetic data.

Non-overlap

This is not another broad extractor/navigation, ontology drift, multilingual alias, temporal consistency, geospatial sample provenance, sample custody/cold-chain, software dependency provenance, image metadata, funding provenance, relationship conflict, measurement harmonization, or evidence freshness slice. It focuses specifically on experiment-to-protocol adherence and graph edge hold/release decisions before entity pages or recommendations publish.

Validation
