[codex] Add enterprise lab inventory sync module

[newmattock]

/claim #19

Addresses #19

Summary

• add a self-contained enterprise lab inventory sync module
• detect ELN/LIMS integration drift, instrument calibration gaps, reagent expiry, reservation conflicts, and export blockers
• emit prioritized admin actions, webhook-style events, export gate decisions, deterministic audit digests, and demo artifacts
• include synthetic lab data, requirement mapping, SVG/GIF demo artifacts, a short MP4 demo video, CLI demo, and Node tests

Distinctness

This slice focuses on lab inventory and instrument-readiness signals feeding enterprise tooling before research exports proceed. It avoids duplicating broad admin dashboards, compliance packets, trust centers, webhook replay ledgers, identity provisioning drift, or generic export pipelines.

Demo

• enterprise-lab-inventory-sync/docs/demo.mp4
• enterprise-lab-inventory-sync/docs/demo.gif
• enterprise-lab-inventory-sync/docs/demo.svg
• cd enterprise-lab-inventory-sync && npm run demo
