Confidence Score: 4/5

The behavioral changes appear safe, but the explicit repository import-order requirement must be satisfied before merging; adding video attachments to the chat lightbox would also complete the advertised media experience.

Findings

1.  Video Lightbox Missing ▶
2.  Import Order Violated ▶

Summary

This PR introduces a shared zoomable media lightbox, relaxes knowledge-base save locking to permit independent concurrent document operations, and repairs workflow loading for legacy loop counts while exposing retryable load errors.

• Consolidates image and video viewing into the EMCN Lightbox and moves wheel-zoom utilities into the shared package.
• Changes connector persistence to hold a shared knowledge-base lock while retaining document-level serialization and deletion safety.
• Normalizes malformed legacy loop counts and adds workflow-load error and retry handling.
• Adds focused unit and PostgreSQL integration coverage for zoom behavior, loop recovery, registry retries, and lock compatibility.
