Add manuscript unit consistency assistant

[YeYe96]

/claim #13

Summary

• Add manuscript-unit-consistency-assistant, a focused AI Peer Review Aid slice for draft manuscript unit hygiene.
• Detect missing units near manuscript quantities, molar-vs-mass concentration conflicts for tracked reagents/outcomes, table header versus cell unit drift, and implausible lab values.
• Emit reviewer actions, readiness scoring, deterministic audit digest, measurement inventory, JSON/Markdown/SVG reports, and a short H.264 MP4 demo artifact.

Non-overlap

This is not the existing knowledge graph measurement harmonization guard, analysis-variable provenance audit, citation metadata/style/diversity assistant, manuscript similarity triage, ethics/data availability auditor, uncertainty calibration checker, biomethods specimen/reagent provenance assistant, or broad grammar pass. It focuses on manuscript unit consistency before submission.

Follow-up verification update: added manuscript-unit-consistency-assistant/reports/demo.mp4 as a short H.264 demo artifact. Local metadata check reports H.264, 4s, 1280x720. Re-ran npm --prefix manuscript-unit-consistency-assistant run check, test, run demo, and git diff --check successfully after the update.
